Description

  The present invention relates to a light emitting device and an electronic device that emit light by electroluminescence.

  An organic light emitting diode (OLED), that is, an organic EL (electro luminescent) element, has attracted attention as a thin and light-emitting source, and an image display apparatus including a large number of organic EL elements has been developed. The organic EL element has a structure in which at least one organic thin film formed of an organic material is sandwiched between a pixel electrode and a counter electrode.

The aforementioned image display device typically has an image display area and its peripheral area on, for example, an element substrate. Here, the image display area is an area in which the above-mentioned many organic EL elements are arranged in a matrix, for example. The peripheral area is provided with a power supply circuit for supplying various signals to the organic EL element, various signal processing circuits, and input / output terminals used for exchanging signals with the outside. .
As such an image display device, for example, a device disclosed in Patent Document 1 is known.
JP-A-2005-251721

  By the way, in the image display apparatus as described above, a laminated structure composed of various elements including the organic EL elements and the like is constructed in the image display area on the element substrate. Here, various elements include, for example, a thin film transistor (TFT) that functions as a constant current source of an organic EL element or functions as a switching element, a capacitor element, a resistance element, various wirings, and these various circuits. An interlayer insulating film for preventing a short circuit between elements may be included.

In such a laminated structure, since the above-described circuit elements and the like have a certain height, irregularities can be formed on the surface portion thereof. The presence of the unevenness causes disconnection when a wiring is formed thereon, or when forming a sealing film for preventing entry of oxygen or moisture into the organic EL element. It is generally considered to be avoided, for example, it causes the sealing film to break.
Therefore, conventionally, a technique for forming a flattening film is known to level out such unevenness.

  However, the flattened film may be made of a material having a certain degree of fluidity in order to realize the role of exposing the flat surface on the upper surface while leveling the unevenness on the lower side. As a result, it is generally difficult to form the planarizing film. This is because there is a high possibility that the planarization film flows out of the substrate. Of course, in preparation for such a situation where the flattening film flows out, it is possible to take a measure of preliminarily enlarging the size of the peripheral region (so-called a region called a frame). However, this obviously increases the overall size of the apparatus.

  Patent Document 1 described above discloses a technique of providing a “buffer layer” corresponding to the above-described “flattening film” and providing a “frame portion that surrounds the periphery” (hereinafter, “”). The inside is Patent Document 1 [Claim 1]. According to this, as has already been pointed out in Patent Document 1, the “out of the buffer layer outside the predetermined region (flow out)” ([0005] of Patent Document 1) is effective to some extent. Can be prevented.

  However, although Patent Document 1 discloses the basic idea of providing a “frame portion” to prevent “buffer layer ... out (flow out)”, the “out (out)” is disclosed. "Is not considered in detail, such as where the element substrate or the laminated structure is likely to occur.

In addition, a specific aspect of the “frame portion” disclosed in Patent Document 1 is “a hydrophilic polymer material (organic resin material)” (Patent Document 1 [0037]) or “organic bank”. It can be formed from “the same material as the layer” (see [0037] or [Claim 8] of Patent Document 1). Such a configuration is significant from the viewpoint of manufacturing the “frame portion” relatively easily, but there is no other possibility.
There are various requirements to be satisfied by the image display device. For example, as in the sealing film described above, one of the requirements is that entry of moisture or the like into the light emitting element should be suppressed. From this point of view, when the aforementioned “frame” is made of an “organic” material, it cannot be said that this requirement is sufficiently satisfied.
In general, if a certain element (in the case of Patent Document 1, the “frame part”) is specially provided, the element has an ambiguous function in order to satisfy more requests among the various requests. It is preferable to have If so, it is because a special material is prepared to provide the element and one process is divided, or the area on the element substrate occupied by the element is more alive.

  The present invention has been made in view of the above-described problems, and provides a light-emitting device and an electronic apparatus that can more effectively prevent the planarization film from flowing out, or that the prevention means can have more functions. The issue is to provide.

  In order to solve the above-described problem, a light-emitting device according to the present invention includes a substrate, a plurality of light-emitting elements formed on the substrate, a planarization film formed to cover the light-emitting elements, and the substrate. And a metal film composed of one or a plurality of layers formed between the substrate and the planarization film and a metal film composed of the one or a plurality of layers. And a damming portion for preventing the flattening film from flowing out, and the damming portion is disposed so as to be located around the flattening film in a plan view.

According to the present invention, since the planarizing film is first formed, the unevenness formed due to the heights of various elements such as the light emitting element and the metal film can be leveled. As a result, it is possible to suitably stack some elements on the planarizing film. In order to better exhibit the function of leveling such irregularities, the planarizing film is preferably a material having relatively high fluidity at least during film formation.
In the present invention, in particular, there is a damming portion around the flattening film. This blocking portion prevents the outflow toward the outside of the substrate even when the planarizing film is made of a material having relatively high fluidity as described above. If this blocking portion does not exist, it is necessary to secure a relatively large peripheral region on the substrate in consideration of a region where the outflow of the planarization film naturally stops. From this point of view, according to the present invention, it is possible to realize a so-called narrowing of the frame region, and thus to achieve a reduction in the size of the entire apparatus.
In addition, since the damming portion according to the present invention is formed of the same layer as the metal film having a relatively high moisture and oxygen sealing function, the moisture and oxygen are prevented from entering the light emitting element. Is done. Thereby, the lifetime improvement of the light emitting element can be achieved.
Note that the metal film according to the present invention is electrically connected to the light emitting element and can be used to supply a current or the like to the light emitting element. In this case, the damming portion is indispensable as such. Since it is formed of the same layer as the metal film which is a key element, the efficiency and simplification of the manufacturing process can also be achieved.

The light emitting device of the present invention may be configured to further include a sealing film that is formed so as to cover the planarizing film and suppresses entry of at least one of moisture and oxygen into the light emitting element.
According to this aspect, since the sealing film is provided, the life of the light emitting element can be extended as compared with the above.
In addition, in this aspect, in particular, as described above, the damming portion is generally formed of the same layer as the metal film having a relatively small height, so the height of the damming portion or the damming portion The height of the convex portion on the surface of the interlayer insulating film on the damming portion formed due to the height of the barrier layer is relatively small. And since the sealing film is formed on the convex part etc. which have such a comparatively small height, the crack etc. in the level | step-difference part have become harder to generate | occur | produce.
In short, according to this aspect, since the blocking portion is formed of the same layer as the metal film, the sealing function by the sealing film can be better enjoyed.

The light emitting device of the present invention further includes a partition formed on the substrate so as to partition each of the plurality of light emitting elements, and the planarization film is formed to cover the partition. You may comprise.
According to this aspect, since the partition is generally an element having a relatively large height, the effect exerted by the planarizing film can be more effectively enjoyed.

In the light-emitting device of the present invention, the plurality of light-emitting elements are formed according to a matrix arrangement on the substrate, and the metal film composed of the one or more layers is flat when viewed in plan. At least a plurality of first wiring films arranged so as to cross a contour line of the insulating film, and the damming portion may be formed on at least a part of the plurality of first wiring films. Good.
According to this aspect, it is typically assumed that the plurality of first wiring films extend from the image display region in which the plurality of light emitting elements are arranged in a matrix to the peripheral region. The plurality of first wiring films intersect with the contour line of the planarization film when viewed in plan. In this case, since the first wiring film has a certain height, a protrusion due to the first wiring film is formed on the surface of an interlayer insulating film or the like formed on the first wiring film.
According to these, on the surface of the interlayer insulating film or the like, a convex portion that extends from the contour line of the planarizing film toward the outside of the substrate and rises to a certain degree as viewed from the periphery is formed. In addition, a plurality of such protrusions are arranged (because there are a plurality of first wiring films).
Such projections relatively facilitate the outflow of the planarization film, as can be inferred from the above-described shape characteristics. In other words, the presence of the convex portion (or the concave portion between the convex portion and the convex portion) can be a disturbance factor of the surface tension on the outer surface of the planarizing film. The flow behavior of the chemical film is promoted.
However, in this aspect, the damming portion is formed on at least a part of the plurality of first wiring films, preferably each of them. Therefore, according to this aspect, it is possible to suppress the outflow of the portion where the outflow of the planarizing film is promoted.
Thus, in this aspect, the effect of preventing the planarization film from flowing out is more effectively achieved.

Note that the “first wiring film” in the present embodiment refers to, for example, “scanning” that supplies a selection signal for selecting light emitting elements located in a certain row among a plurality of light emitting elements arranged in a matrix. A “line” or a “data line” for supplying an image signal to the plurality of light-emitting elements may be applicable.
Further, in this aspect, the damming portion is formed “at least on a part of the plurality of first wiring films”, and that the metal film includes “the first wiring film”, and The fact that the blocking portion is formed of the same layer as the “metal film” includes the following specific examples. That is, when the blocking portion is formed of the same layer as the first wiring film as a part of the metal film (this will be described later), or the blocking portion is the first wiring film. In the case where such a damming portion is formed “for each of the first wiring films”, and so on. A more specific example of the latter of these will be described as <Sixth Embodiment> in the description of the later embodiments.

In this aspect, the damming portion is formed of the same layer as the first wiring film, and the damming portions of the plurality of first wiring films are not electrically connected to each other. May be.
According to this, the damming portion is formed of the same layer as the first wiring film among the “metal films” that may include various types. And the said damming part is formed about at least one part of several 1st wiring films, and since the damming part is not electrically connected mutually, these several 1st wiring films are dammed together. There is no situation of an electrical short circuit through the part. Accordingly, it is possible to accurately and reliably supply a signal or the like to the light emitting element.

In this aspect, the damming portion may further include an intersecting portion extending in a direction intersecting with the extending direction of the first wiring film.
According to this, since the damming portion includes the intersecting portion, the effect of preventing the flattening film from flowing out is more effectively exhibited.

In this aspect, the damming portion further includes the first wiring films adjacent to each other so as to fill a gap between the two intersecting portions of the first wiring films adjacent to each other among the plurality of first wiring films. You may comprise so that the auxiliary | assistant part formed in between may be included further.
According to this, since the blocking portion includes the auxiliary portion as described above, it is possible to block the flow operation of the flattening film that flows out through the gap between the intersecting portions. . That is, according to this configuration, the effect of preventing the outflow of the planarizing film is more effectively achieved than the above.

Alternatively, in an aspect in which the blocking portion includes the “intersection portion”, the formation position of the intersection portion with respect to a certain first wiring film among the plurality of first wiring films corresponds to the certain first wiring film. You may comprise so that it may differ from the formation position of the said intersection part about an adjacent 1st wiring film.
According to this aspect, since the formation positions of both intersecting portions of the adjacent first wiring films are different from each other, it is possible to perform a so-called stepwise suppression against the outflow of the planarization film. For example, an intersection that is closer to the contour line of the planarization film performs a first-stage suppression, and a farther intersection intersects a second-stage suppression.

In this aspect, the formation position of the intersecting portion of the first wiring film (excluding the certain first wiring film) further adjacent to the adjacent first wiring film is the position of the certain first wiring film. You may comprise so that it may be the same as the formation position of the said intersection part.
According to this, when each of the first wiring films constituting the plurality of first wiring films is viewed in order from the end, the intersections of the respective first wiring films are alternately arranged in steps. Can typically appear. That is, the intersection of the first first wiring film is closer to the contour line of the planarization film, the intersection of the next first wiring film is further away, and the intersection of the subsequent first wiring film is closer. It is.
According to such a form, the step-wise suppression with respect to the outflow of the planarization film | membrane mentioned above is performed better.

Alternatively, in an aspect in which the formation positions of both intersecting portions of the adjacent first wiring films are different from each other, at least a part of the intersecting portions with respect to the certain first wiring film and the intersecting with respect to the adjacent first wiring films. At least a part of the portion is configured to intersect with a certain straight line extending between the two first wiring films and in parallel along the extending direction of the first wiring film. May be.
According to this aspect, since the intersecting portion of the adjacent first wiring films intersects the one straight line, a so-called labyrinth seal can be configured by the first wiring film and the intersecting portion. It has become. That is, for example, a flattening film that flows out around an end of an intersection of a certain first wiring film is prevented from flowing out by the intersection of the first wiring film adjacent to the certain first wiring film. It will be said.
In this way, according to this aspect, the effect of preventing the flattening film from flowing out is extremely effectively achieved.

In the light emitting device of the present invention, the blocking portion receives an opening for receiving the planarization film flowing out along the first wiring film, and receives the planarization film flowing in through the opening. And a receiving portion.
According to this aspect, since the dam portion includes the opening and the receiving portion, a certain amount of the planarized film that has flowed out can be maintained. Thereby, even if a relatively large amount of the planarizing film flows out, the progress can be stopped at the position where the blocking portion is formed.
According to this aspect, in this way, the effect of preventing the flattening film from flowing out is effectively achieved.

In this aspect, the damming portion may have a wedge shape in plan view.
According to this, if the blocking portion is formed so that the portion opposite to the wedge-shaped pointed portion is directed to the contour line of the planarizing film, the above-described planarization film outflow prevention effect is more effective. Can be demonstrated.
Alternatively, in this aspect, the damming portion has a first side portion that is a portion intersecting the first wiring film in a plan view and an extending direction of the first wiring film from both ends of the first side portion. And the opening corresponds to a space between the ends of the two second sides, and the receiving portion includes the first side and the two sides. You may comprise so that the space enclosed by the 2nd edge part may correspond.
This also makes it possible to more effectively exert the above-described effect of preventing the flattening film from flowing out.
In the aspect in which the damming portion has the first side portion and the second side portion, the first wiring film having the damming portion having the first side portion and the second side portion is adjacent to the first wiring film. The damming portion for one wiring film has a third side portion that intersects the first wiring film adjacent to each other in plan view and the first wiring adjacent to each other from both ends of the third side portion. Two fourth sides extending in a direction in which the film extends and in a direction opposite to the direction in which the second side extends, and the second side includes the fourth side and the phase. You may comprise so that it may be located between adjacent 1st wiring films.
According to this, what is called a labyrinth seal can be comprised by the adjacent 1st wiring film and those damming parts. That is, even if the planarizing film dammed up at the third side portion flows to the outside of the substrate through the fourth side portion connected to the third side portion, It will only flow into the opening that constitutes the damming part, and is subsequently dammed by the first side that constitutes the damming part (note that the planarization film is moved out of the substrate). If it is intended to flow out, the planarization film must pass through the bottleneck between the second side and the fourth side as if flowing backward.
In this way, according to this aspect, the effect of preventing the flattening film from flowing out is extremely effectively achieved.
An example of a more specific aspect relating to each of these aspects will be described again in the following embodiments with reference to the drawings.

Alternatively, the light emitting device of the present invention may be configured such that the first wiring film includes a bent portion as viewed along the extending direction, and the damming portion includes the bent portion.
According to this aspect, the blocking portion includes the bent portion of the first wiring film itself. Even in such a form, the outflow of the flattening film encounters a certain obstacle at the bent portion, so that the outflow prevention effect is exhibited.

Alternatively, in the light emitting device of the present invention, the metal film composed of the one or more layers extends in a direction intersecting with the extending direction of the first wiring film, and has an outline of the planarizing film in plan view. A plurality of second wiring films formed on the substrate with at least one interlayer insulating film interposed between the first wiring films and the plurality of second wiring films. The damming portion formed for one wiring film may be formed in the same layer as the second wiring portion.
According to this aspect, as described above, the dam portion “formed on at least a part of the first wiring film” is the same as the “second wiring film” among the “metal films” that may include various types. Formed in layers. Even in such a case, the damming portion is still formed of the same layer as the metal film, and thus the effect according to the present invention described above is also achieved. Absent.
Further, according to this, for example, it is conceivable that a laminated structure in the order of the first wiring film, the interlayer insulating film, and the second wiring film is constructed on the substrate. In this case, for example, the first wiring film For each of the films, as described above, the damming portion is formed in the same layer as the second wiring film, and for each of the second wiring films, the damming portion is formed in the same layer as the second wiring film. It can be formed. Thus, according to this aspect, the damming portion can be suitably formed for all of the first and second wiring films.
The “second wiring film” referred to in this embodiment may correspond to, for example, the above-mentioned “data line”, and the “first wiring film” in that case may correspond to, for example, the above-described “scanning line”. .

In this aspect, the damming portion includes an intersecting portion extending in a direction intersecting with the extending direction of the first wiring film, and the intersecting portion includes two or more first of the plurality of first wiring films. You may comprise so that it may cross | intersect a wiring film.
According to this, the damming portion formed in the same layer as the second wiring film includes an intersecting portion that intersects two or more first wiring films. According to this, the damming portion for each of the plurality of first wiring films has a continuous or integral form like a wall with respect to all of the first wiring films. Can be more effectively prevented.
Even if it takes such a form, since the second wiring film is formed as a layer different from the first wiring film, there is no problem of short circuit between the plurality of first wiring films.

On the other hand, in order to solve the above-described problems, an electronic apparatus according to the present invention includes the various light-emitting devices described above.
According to the present invention, since the various light emitting devices described above, that is, the light emitting device that has been reduced in size as a result of preventing the outflow of the planarization film is provided, the electronic device can be downsized. Can be done.
Further, as described above, the damming portion for preventing the flattening film from flowing out is formed of the same layer as the metal film, so that the lifetime of the light emitting element can be increased. In particular, it is possible to improve the reliability related to deterioration over time. Thereby, for example, if the electronic apparatus according to the present invention includes the above-described various light emitting devices as an illumination device for an image display device, a higher quality image can be displayed.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 8. In these drawings and the drawings after FIG. 10 to be referred to later, the ratio of the dimensions of each part is appropriately changed from the actual one.

The image display area 7 a is an area where the plurality of organic EL elements 8 are arranged on the element substrate 7. In the image display area 7 a, a desired image can be displayed based on individual light emission and non-light emission of each organic EL element 8. In the following, for convenience of explanation, the area excluding the image display area 7a in the surface of the element substrate 7 may be referred to as “peripheral area” (the “image display area 7a” in the first embodiment, I will touch on more detailed definitions later.)

  The scanning lines 3 and the data lines 6 are arranged so as to correspond to the respective rows and columns of the organic EL elements 8 arranged in a matrix.

In the unit circuit P, when the scanning line driving circuits 103A and 103B select the scanning line 3 corresponding to the unit circuit P, the first transistor 68 is turned on, and the data signal supplied via the data line 6 is transferred to the internal circuit P. It is held in the capacitor element 69. Then, the second transistor 9 supplies a current corresponding to the level of the data signal to the organic EL element 8. As a result, the organic EL element 8 emits light with a luminance corresponding to the level of the data signal.

On the peripheral region on the element substrate 7, a precharge circuit 106A is provided. The precharge circuit 106A is a circuit for setting the data line 6 to a predetermined potential prior to a data signal write operation to the organic EL element 8.

Among these, the gate insulating film 300 and the first to fourth interlayer insulating films 301 to 304 (hereinafter simply referred to as “insulating films 300 to 304”) do not cause a short circuit between the remaining conductive elements. Alternatively, the present invention contributes to realizing a suitable arrangement of these conductive elements in the laminated structure 250. Although these insulating films 300 to 304 can be made of various insulating materials with various thicknesses, it is preferable that the insulating films 300 to 304 are appropriately selected depending on the arrangement position and role of each insulating film in the laminated structure 250. A suitable thickness and material may be selected.
More specifically, for example, the gate insulating film 300 and the first to third interlayer insulating films 301 to 303 are preferably made of an inorganic insulating film such as SiO ₂ , SiN, or SiON. The fourth interlayer insulating film 304 is preferably made of an organic insulating film such as an acrylic resin because it includes a partition wall 340 described later.

As shown in FIG. 3, each of the organic EL elements 8 includes the pixel electrode 13, the light emitting functional layer 18, and the counter electrode 5 among the various elements included in the stacked structure 250.
Among these, the pixel electrodes 13 are formed on the element substrate 7 so as to be arranged in a matrix. The fact that the organic EL elements 8 are arranged in a matrix corresponds to the fact that the pixel electrodes 13 are arranged in a matrix as described above (see FIGS. 1 and 3).
The pixel electrode 13 is electrically connected to the relay line 61 through the contact hole 363. Thereby, the pixel electrode 13 can apply the current supplied from the current supply line 113 via the second transistor 9 to the light emitting functional layer 18. The contact hole 363 is formed so as to penetrate the second and third interlayer insulating films 302 and 303.

A reflective layer 34 is formed on the second interlayer insulating film 302 and below the third interlayer insulating film 303 so as to correspond to the formation region of the pixel electrode 13. The reflective layer 34 reflects the light emitted from the light emitting functional layer 18. This reflected light travels upward in the figure as shown in FIG. Such a reflective layer 34 is preferably made of a material having a relatively high light reflection performance in order to better exhibit the above-described reflection function. For example, a metal such as aluminum or silver can be used.
On the other hand, in a plan view, a partition (bank) 340 is formed in a region between adjacent pixel electrodes 13 as shown in FIG. The partition 340 is formed as the fourth interlayer insulating film 304 or at least a part thereof. Such a partition 340 is preferably made of, for example, an insulating transparent resin material, and more specifically, is preferably made of, for example, an epoxy resin or polyimide other than the acrylic resin already described ( As a result, the fourth interlayer insulating film 304 is also made of these materials.)

As shown in FIG. 3, the light emitting functional layer 18 is formed on the pixel electrode 13 so as to cover the surface of the element substrate 7, in particular, the image display region 7a.
The light emitting functional layer 18 includes at least an organic light emitting layer, and the organic light emitting layer is composed of an organic EL material that emits light by combining holes and electrons. In FIG. 3, the organic EL material is a low molecular material and is formed by an appropriate film forming method. As other layers constituting the light-emitting functional layer 18, part or all of an electron block layer, a hole injection layer, a hole transport layer, an electron transport layer, an electron injection layer, and a hole block layer may be provided.
In the first embodiment, the light emitting functional layer 18 emits white light uniformly.

The organic EL material described above may be a polymer material. In this case, for example, as shown in FIG. 4, the organic EL material can be supplied only in each space partitioned by the partition 340 (that is, for each pixel). In FIG. 4, the organic EL material constitutes all or part of the light emitting functional layer 18 ′. The organic EL substance as the polymer material can be supplied into the space by a liquid supply method such as an ink jet method or a dispenser method.
As described above, according to the aspect in which the organic EL material is supplied only to the space partitioned by the partition wall 340, the light emitting functional layer can be provided separately for each color. That is, for each space, for example, it is possible to form a light emitting functional layer including organic EL materials dedicated to red light, green light, and blue light.

The counter electrode 5 is in contact with the light emitting functional layer 18 of the plurality of organic EL elements 8. That is, the counter electrode 5 extends over the area of the light emitting functional layer 18 defined by the partition 340 and the partition 340 so as to be common to the plurality of pixel electrodes 13. The counter electrode 5 is formed in a rectangular shape (in particular, it has no special opening, gap, etc., so-called solid). In this embodiment, the pixel electrode 13 is an anode and the counter electrode 5 is a cathode, but vice versa.
Such a counter electrode 5 is made of a translucent and conductive material such as ITO (Indium Tin Oxide).

As shown in FIG. 5, each of the first transistors 68 included in the unit circuit P includes a semiconductor layer 1 ′ formed as the same layer as the semiconductor layer 1, a gate insulating film 300, and the gate metal 37. The scanning line 3 is formed as the same layer.
Similarly to the second transistor 9, the first transistor 68 is also a thin film transistor.
However, it is not the gate metal 37 but the scanning line 3 that functions as the gate electrode in the first transistor 68. As shown in FIG. 5, the scanning line 3 is formed on the gate insulating film 300 so as to correspond to the channel region of the semiconductor layer 1 ′.
A gate metal 37 functioning as a gate electrode of the second transistor 9 is connected to the drain region of the semiconductor layer 1 ′ of the first transistor 68, and the data line 6 is connected to the source region thereof. Among these, as can be seen from FIG. 5, the data line 6 is formed on the first interlayer insulating film 301 as the same layer as the relay line 61 and the current supply line 113 described above.

  By the first transistor 68, the second transistor 9, and the organic EL element 8, a current is caused to flow between the pixel electrode 13 and the counter electrode 5, and at the same time, a current is caused to flow to the light emitting functional layer 18. The layer 18 emits light (see also the explanation already given with reference to FIG. 2). In addition, since the light emitted from the light emitting functional layer 18 travels to the side opposite to the side where the element substrate 7 exists due to the presence of the reflective layer 34, the organic EL device according to the first embodiment. Is a so-called top emission type. For this reason, the element substrate 7 does not necessarily need to be made from a translucent material. Specifically, it may be an opaque material such as ceramics or metal, but there is no particular reason that it should not be a translucent material such as glass.

The organic EL device according to the first embodiment is particularly characterized with respect to the data line 6 among the various elements described above.
As described above, the data line 6 functionally supplies a data signal to the gate of the second transistor 9 so that a current flowing between the source and drain of the second transistor 9 (that is, the organic EL). Element for adjusting the magnitude of the current flowing in the element 8 (see FIG. 2), and is structurally formed between the first interlayer insulating film 301 and the second interlayer insulating film 302, and is an organic EL It is positioned as a metal wiring thin film having an electrical connection relationship with the element 8 (see FIG. 5).
In addition to this, the data line 6 according to the first embodiment also has a function of preventing the planarization film 80 from flowing out of the element substrate 7 and a configuration suitable for it. Hereinafter, matters related to this function will be described in detail.

First, as the premise, in the organic EL device of the first embodiment, it will be described that the planarizing film 80 described above is included in the elements constituting the stacked structure 250.
As shown in FIG. 3 and the like, the planarizing film 80 is formed on the counter electrode 5 (or directly on the fourth interlayer insulating film 304 on the right side of FIG. 6), the surface of the element substrate 7, In particular, it is formed so as to cover the entire image display area 7a.
Such a planarizing film 80 is made of a material having a relatively large fluidity at least during film formation. Therefore, the unevenness formed due to the various elements constituting the laminated structure 250, particularly the height of the partition 340, is leveled. FIG. 3 shows a state in which the planarizing film 80 levels the unevenness appearing on the upper surface of the counter electrode 5 in the drawing due to the partition 340 and the like.
As a result, some elements can be suitably stacked on the planarizing film 80. In addition, the planarization film 80 relieves stress generated due to warpage and volume expansion generated in the stacked structure 250 positioned below the counter electrode 5. Further, the planarizing film 80 prevents the counter electrode 5 from being peeled off from the partition wall 340.

More specifically, examples of the material constituting the planarizing film 80 include lipophilic polymer materials (organic resin materials) such as polyolefin resins, polyether resins, epoxy resins, and acrylics. It is preferable to use resin, silicone resin, polyurethane, polyether, polyester or the like. More specifically, acrylic polyol, polyester polyol, polyether polyol, polyurethane polyol and a derivative obtained by mixing and polymerizing an isocyanate compound such as tolylene diisocyanate or xylylene diisocyanate, or a bisphenol type epoxy oligomer and an amine compound are mixed. And polymerized derivatives.
These organic compounds are diluted with a lipophilic organic solvent such as toluene, xylene, cyclohexane, methyl ethyl ketone, and ethyl acetate, adjusted to a predetermined viscosity, and formed on the counter electrode 5 as an epoxy oligomer, acrylic oligomer, polyurethane, or the like. Be placed.
In addition, an isocyanate compound raise | generates a urea coupling | bonding reaction by reacting with a water | moisture content, and polymerizes. By this reaction, moisture remaining in the planarizing film 80 is fixed, so that moisture can be prevented from entering the counter electrode 5 and the light emitting functional layer 18.

By the way, such a flattening film 80 is made of a material having relatively high fluidity as described above, and therefore tends to flow out of the element substrate 7. In particular, in the first embodiment, the presence of the convex portion 331 as shown in FIG. 6 or FIG. 7 relatively facilitates the outflow of the planarizing film 80.
Here, the convex portion 331 is formed on the surface of the third interlayer insulating film 303 due to the height of the data line 6. As shown in FIG. 1 or FIG. 5 or the like already referred to, a plurality of data lines 6 are arranged so as to correspond to each column of the plurality of organic EL elements 8 arranged in a matrix. Also, as shown in FIG. 7, a plurality are arranged. Further, the data line 6 extends from the image display area 7a to the peripheral area for electrical connection with the data line driving circuit 106 or the connection terminal described above. Therefore, the plurality of convex portions 331 also extend from the image display region 7a to the peripheral region while intersecting with the contour line of the planarizing film 80 when seen in a plan view.
Note that the “image display region 7a” is defined as a region where a plurality of organic EL elements 8 are arranged, but more strictly speaking, the counter electrode is more specifically described with reference to FIG. 5 is defined as a formation region. However, although it is “strict”, this promise is merely intended to cause confusion of meanings, and is valid as long as it relates to each embodiment of the present invention (in other words, other definitions) There is also a possibility.)

As can be inferred from the shape characteristics of the convex portion 331 as described above, the convex portion 331 can be a disturbance factor of the surface tension on the outer surface of the planarizing film 80, resulting in the outflow of the planarizing film 80. This is relatively accelerated (see reference numeral “80OZ” in FIG. 7).
Therefore, in the organic EL device according to the first embodiment, as shown in FIGS. 6 and 7, the damming portion 601 is provided for each of the plurality of data lines 6 in order to prevent the outflow of the planarization film 80. Is formed. In FIG. 1, the position where the blocking portion 601 is to be formed when viewed from the viewpoint of the entire apparatus is shown as a region surrounded by a broken line with a symbol AEL.
The blocking portion 601 is formed as the same layer as the data line 6. Therefore, its physical thickness is the same as that of the data line 6 and is generally relatively thin.
Further, the blocking portion 601 is formed so as to intersect the extending direction of the data line 6. Particularly in the first embodiment, the blocking portion 601 extends in a direction orthogonal to the extending direction of the data line 6.
Furthermore, the blocking portions 601 are individually formed according to the data lines 6 as shown in FIG. 7, and the blocking portions 601 are not electrically connected to each other. In FIG. 7, physical gaps are provided between the respective damming portions 601 (the gaps are filled with the second interlayer insulating film 302), thereby preventing electrical connection therebetween. As a result, each data line 6 can be supplied with a unique data signal accurately and reliably, and no electrical short circuit occurs between the data lines 6.

  Since the second interlayer insulating film 302 is formed on the damming portion 601 and the data line 6 and the third interlayer insulating film 303 is further formed on the second interlayer insulating film 302, the surface thereof is caused by each. A convex part is formed. For the latter, the convex portion 331 described above corresponds to that, but for the former, as shown in FIG. 6 and FIG. Basically, the dike portion 91 inherits the shape characteristic of the damming portion 601, so that it extends so as to be orthogonal to the extending direction of the convex portion 331, and is adjacent to each other. Both the dike portions 91 in the convex portion 331 are not connected to each other. However, for the latter, if the distance between the end portions of both damming portions 601 is appropriately set, as shown in FIG. 7, the connection between both dyke portions 91 corresponding to these both damming portions 601; Alternatively, overlapping can be realized. This is based on the natural property that, in general, the size of the convex portion formed on the surface of the insulating film is one size larger than the size of a certain element that causes it.

As described above, the organic EL device according to the first embodiment has the following effects.
(1) First, due to the presence of the blocking portion 601 and the dike portion 91, the effect of preventing the flattening film 80 from flowing out is exhibited. In particular, if the connection between the bank portions 91 described above is achieved, it is possible to better enjoy the effect while preventing a short circuit between the data lines 6.
That is, as shown in FIGS. 6 and 7, the planarization film 80 is formed on the fourth interlayer insulating film 304 and beyond the film edge 304E in the peripheral region. As described above, it flows out along the convex portion 331 and toward the outside of the element substrate 7, but the damming portion 601 and the bank portion 91 block the outflow (see reference numeral X <b> 1 in FIG. 6). ). Thus, in the first embodiment, the outflow of the portion where the outflow of the planarization film 80 is promoted can be suppressed.
Such an effect can be understood more clearly when compared with FIG. 8 which is a comparative example. In FIG. 8, the dam portion 601 and the bank portion 91 do not exist, and the stop of the outflow of the planarizing film 80 is only waiting for its natural hardening or the like. In this case, it is necessary to secure a relatively large peripheral area.
According to the first embodiment, since there is no risk of suffering such a problem, it is possible to realize relative narrowing of the peripheral area, that is, so-called narrowing of the frame area. This also makes it possible to reduce the size of the entire apparatus.

(2) In the first embodiment, since the blocking portion 601 is formed as the same layer as the data line 6 as a metal wiring thin film, the sealing function of moisture and oxygen is relatively high. That is, as shown by the arrow with the sign “G” in FIGS. 6 and 7, the entry of moisture and oxygen entering from the side end of the organic EL device is suppressed. Thereby, the lifetime extension of the organic EL element 8 is achieved.

(3) In relation to the suppression of the ingress of moisture and oxygen, the first embodiment includes the sealing film 40 that has already been described above but has not been described yet.
As shown in FIGS. 3 to 6, the sealing film 40 covers the surface of the element substrate 7, particularly at least the planarizing film 80, and the damming portion 601 and the bank portion 91, on the planarizing film 80. Is formed. The sealing film 40 is made of, for example, SiN (silicon nitride), SiON (silicon oxynitride), SiO ₂ , or even Al ₂ O ₃ (alumina), Ta ₂ O ₅ (tantalum oxide), TiO ₂ (titanium oxide), Further, it is preferably made of other ceramics.
Such a sealing film 40 suppresses the ingress of moisture and oxygen into the organic EL element 8 or the light emitting functional layer 18. Therefore, the life of the organic EL element 8 can be extended also by this.

By the way, such a sealing film 40 has a comparatively large hardness and often lacks flexibility from the materials described above. Therefore, if the sealing film 40 is formed so as to stride over a very large step, cracks or the like are likely to occur in a portion covering the step.
In this regard, first, in the first embodiment, since the sealing film 40 is formed so as to cover the planarizing film 80, the risk of suffering such a problem is extremely reduced.
However, since the above-described levee portion 91 is a convex portion formed to prevent the planarization film 80 from flowing out, the sealing film 40 is formed as long as the sealing film 40 is formed on the planarization film 80. The stop film 40 is inevitably formed so as to cover the embankment 91 as well.
However, in the first embodiment, the damming portion 601 that causes the formation of the dyke portion 91 is formed as the same layer as the data line 6 as a metal wiring thin film having a relatively small thickness. Therefore, the height of the bank portion 91 is also suppressed as compared with the case where a blocking portion having the same meaning as the blocking portion 601 is formed as the same layer as the fourth interlayer insulating film 304, for example.
As a result, the sealing film 40 only needs to straddle a relatively small level difference, and therefore the crack or the like is hardly generated in the sealing film 40.

  For this reason, the damming portion 601 and the embankment portion 91 according to the first embodiment achieve the effect of the above (2) while the main effect is the outflow prevention effect of the planarization film 80 of the above (1). In addition, coupled with the maintenance function of the sealing film 40 just described, the effect of suppressing the ingress of oxygen and moisture is also exhibited.

Note that the sealing film 40 may have a two-layer structure of, for example, silicon nitride and silicon oxynitride, or a structure in which the above silicon compound such as ITO and silicon oxynitride is included and stacked with different materials. By forming the base layer made of an inorganic compound in this way, adhesion can be improved, stress can be relaxed, and the denseness of the gas barrier layer made of a silicon compound can be improved.
In addition, the second interlayer insulating film 302 shown in FIG. 3 or the like described above may have a stacked structure of a SiN film on the lower layer side and an acrylic resin film on the upper layer side. The purpose of this is to provide the former with the function of preventing the separation of hydrogen of the semiconductor layer 1 and the like of the second transistor 9 and the latter with the function of flattening the formation surface of the pixel electrode 13. In this case, since the upper layer of the second interlayer insulating film 302 is made of an organic insulating film called acrylic resin, the function of sealing oxygen and moisture is slightly inferior.
Therefore, in such a case, for example, as shown in FIG. 9, the film end 302E of the second interlayer insulating film 302 (or at least the acrylic resin film as the upper layer) is formed at the fourth interlayer insulating film of FIG. It may be formed so as to coincide with the position of the film end 304E of the film 304. In this way, the bank portion 91 is formed from the damming portion 601 formed of the same layer as the metal film and the third interlayer insulating film 303 which is an inorganic insulating film formed on the dam portion 601. In addition, the moisture sealing function can be suitably maintained.
From the above, generally speaking, it can be said that the “damming portion” in the present invention is preferably “formed of a layer below the organic insulating film”. This is because, if this is satisfied, the sealing function of oxygen and moisture can be suitably maintained by adjusting the film edge as described above related to the organic insulating film.

Second Embodiment
Hereinafter, an organic EL device according to a second embodiment of the present invention will be described with reference to FIG.
The basic configuration of the organic EL device in the second embodiment and the third and subsequent embodiments described later is substantially the same as the organic EL device of the first embodiment. Therefore, in the following, the reference numerals of the drawings related to the parts common to both are used in common, and the description thereof is omitted.

As shown in FIG. 10, the organic EL device of the second embodiment has a damming portion 602 having a form different from the damming portion 601 of the first embodiment.
The damming portion 602 is formed as the same layer as the data line 6 as compared with the damming portion 601, extends in a direction orthogonal to the extending direction of the data line 6, and each data line 6 It is the same that they are individually formed according to the above and that the respective damming portions 602 are not electrically connected to each other.

  However, as shown in FIG. 10, in this damming portion 602, the formation positions of both damming portions 602 of the adjacent data lines 6 are different from each other. In addition, when each of the data lines 6 is viewed in order from the end, the respective damming portions 602 are formed so as to be alternately arranged in steps. That is, the damming portion 602 of the leftmost data line 6 in FIG. 10 is closer to the contour line of the planarizing film 80 in plan view, the damming portion 602 of the data line 6 adjacent to the right is farther, The damming portion 602 of the right data line 6 (the rightmost data line 6 in FIG. 10) is closer. At this time, the formation positions of the respective blocking portions 602 of the leftmost data line 6 in FIG. 10 and the rightmost data line 6 in the figure are the same.

Further, the following features are also provided between the blocking portions 602 of the data lines 6. That is, a damming portion 602 of a certain data line 6 (hereinafter also referred to as “first damming portion 602”) and a damming portion 602 of the data line 6 adjacent thereto (hereinafter referred to as “second damming portion”). 602 ") intersects a reference straight line extending in parallel between the two data lines 6 and along the extending direction of the data lines 6. In FIG. 10, an example of the reference straight line NL is displayed between the rightmost data line 6 in the drawing and the middle data line 6 in the drawing with a two-point difference line.
In short, in this case, the first damming portion 602 and the second damming portion 602 overlap each other when viewed along the extending direction of the data line 6.
Accordingly, it can be considered that the first damming portion 602 and the second damming portion 602 constitute a so-called labyrinth seal. In other words, if the planarization film 80 flows out of the element substrate 7 beyond the first and second damming portions 602 (the first damming portion 602 is the second damming portion). Assuming that the flattening film 80 is closer to the contour line of the flattening film 80 than the stop portion 602, the flow of the flattening film 80 is first blocked at the upper surface of the first damming portion 602 in the figure, Secondly, even if this wraps around the end of the first damming portion 602, the flow is blocked at the upper surface of the second damming portion 602 in the drawing, and thirdly, it is attempted to move forward from there. For example, the end of the second damming portion 602 must be reached through a bottleneck between the first damming portion 602 and the second damming portion 602.

It is apparent that the second embodiment also has an effect that is essentially the same as the effect of the first embodiment. This is because, in this second embodiment as well, as described above, the damming portion 602 is formed as the same layer as the data line 6 in comparison with the damming portion 601. Because it has.
In FIG. 10, as shown in FIG. 7, the third interlayer insulating film 303 is formed on the damming portion 602, and the bank portion is formed at an appropriate position on the surface. Although not changed, the illustration is omitted. This also applies to FIGS. 11, 13, 14, 15, 17, 18, and 19 to be referred to later.

  Moreover, in the second embodiment, the effect of preventing the outflow of the planarizing film 80 can be more effectively achieved than in the case of the first embodiment. This is because, in the second embodiment, since the blocking portions 602 are arranged in a “step difference” as described above, for example, the data line in the middle in FIG. 10 that is closer to the contour line of the planarization film 80. 6 damming portion 602 performs the first stage deterrence and keeps behind it, and the remaining two data line 6 damming parts 602 in the figure prevent the second stage deterrence. This is because the effect can be expected (see the arrow in FIG. 10).

  In addition, in the second embodiment, the damming portion 602 forms a labyrinth seal, so that the planarization film 80 that flows out toward the outside of the element substrate 7 has a relatively complicated path. Unless it passes through, it cannot flow out beyond the obstacle of the blocking portion 602. In short, in the second embodiment, the effect of preventing the flattening film 80 from flowing out is very effectively achieved.

<Third Embodiment>
Hereinafter, an organic EL device according to a third embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 11, the organic EL device of the third embodiment includes the same damming portion 601 as the damming portion 601 of the first embodiment, but in addition to this, an auxiliary damming portion 603 is provided. Have.
It is the same that the auxiliary damming portion 603 is formed as the same layer as the data line 6 as compared with the damming portion 601.

However, the auxiliary damming portion 603 is formed between the adjacent data lines 6 so as to fill a gap between the two damming portions 601 for the adjacent data lines 6 as shown in FIG. ing. The auxiliary damming portion 603 is not electrically connected to the adjacent data lines 6 and the respective damming portions 601.
The auxiliary damming portion 603 is formed so as to be substantially parallel to the damming portion 601. That is, if both ends of the auxiliary damming portion 603 in the drawing are temporarily extended, the extended portions intersect the adjacent data lines 6 at right angles.
Further, the position where each auxiliary damming portion 603 is formed is the same from the viewpoint of the extending direction of the data line 6.

  Obviously, the third embodiment also has an effect that is essentially the same as that of the first embodiment. This is because the third embodiment is also provided with the same damming portion 601 as in the first embodiment.

  In addition, in the third embodiment, the effect of preventing the outflow of the planarizing film 80 can be more effectively achieved than in the case of the first embodiment. This is because, in the third embodiment, since the auxiliary damming portion 603 is formed, for example, the damming portion 601 that is closer to the contour line of the planarization film 80 performs the first step suppression, and behind it. This is because it is possible to expect an outflow prevention action such that the auxiliary damming portion 603 performs the second-stage deterrence (see the arrow in FIG. 11). That is, in the third embodiment, the flow operation of the planarizing film 80 that flows out through the gap between the blocking portions 601 in the first embodiment can be blocked.

  In addition, also in the third embodiment, since the damming portion 601 and the auxiliary damming portion 603 form a so-called labyrinth seal as in the second embodiment, the element substrate 7 is directed outward. The flattening film 80 which is about to flow out cannot flow outward beyond the obstacles of the damming portion 601 and the auxiliary damming portion 603 unless they pass through a relatively complicated path. Thus, also in the third embodiment, the effect of preventing the flattening film 80 from flowing out is very effectively achieved.

<Fourth embodiment>
Hereinafter, an organic EL device according to a fourth embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 12 and 13, the organic EL device of the fourth embodiment has a damming portion 604 that performs the same function as the damming portion 601 of the first embodiment.
It is the same that the damming portion 604 is formed as the same layer as the data line 6 in contrast to the damming portion 601.

However, the blocking portion 604 is not formed for each of the data lines 6, but is formed for each of the scanning lines 3, as shown in FIGS.
The scanning line 3 causes the formation of the convex portion 332 shown in FIG. 12, similarly to the relationship that the data line 6 causes the formation of the convex portion 331 described above. That is, as shown in FIG. 1 or FIG. 5 or the like already referred to, a plurality of the scanning lines 3 are arranged so as to correspond to each row of the plurality of organic EL elements 8 arranged in a matrix. A plurality of 332 are also arranged. Further, the scanning line 3 extends from the image display area 7a to the peripheral area for electrical connection with the above-described scanning line driving circuits 103A and 103B or connection terminals. Therefore, the plurality of convex portions 332 also extend from the image display region 7a to the peripheral region while intersecting with the contour line of the planarizing film 80 when seen in a plan view.
Eventually, the outflow phenomenon of the planarizing film 80 can also occur along the convex portion 332 caused by the scanning line 3.

Therefore, in the organic EL device according to the fourth embodiment, in order to prevent the outflow of the planarizing film 80, as shown in FIG. 12 and FIG. (Hereinafter referred to as “scanning line damming portion 604”).
The scanning line corresponding blocking portion 604 is formed so as to intersect the extending direction of the scanning line 3. Particularly in the fourth embodiment, the scanning line corresponding blocking portion 604 extends in a direction orthogonal to the extending direction of the scanning line 3.
Further, the scanning line corresponding blocking portions 604 are individually formed according to the respective scanning lines 3 as shown in FIG.

  A second interlayer insulating film 302 is formed on the scanning line corresponding damming portion 604 and the scanning line 3, and a third interlayer insulating film 303 is further formed on the second interlayer insulating film 302. Since the first interlayer insulating film 301 is also formed), a convex portion due to each is formed on the surface of the third interlayer insulating film 303. For the latter, the above-described convex portion 332 corresponds to that, but for the former, as shown in FIG. 12, the embankment portion 94 corresponds to that. This levee portion 94 basically inherits the shape characteristic of the scanning line corresponding damming portion 604, so that it extends so as to be orthogonal to the extending direction of the convex portion 332. The two bank portions 94 in the adjacent convex portion 332 are not connected to each other. However, if the distance between the end portions of the damming portion 604 is appropriately set, the connection between the two levee portions 94 corresponding to the both damming portions 604 or the overlapping can be realized. This is the same as in the first embodiment.

It is apparent that the fourth embodiment also has the effects that are essentially the same as the effects achieved by the first embodiment. This is because, in the fourth embodiment, the scanning line corresponding damming portion 604 (or the relationship between this and the scanning line 3) is the damming portion 601 (or this and the data line 6) as described above. This is because it has many common matters such as being formed as the same layer as the data line 6.
In particular, the fourth embodiment is characterized in that the outflow of the planarization film 80 along the data line 6 is not prevented, but it is prevented along the scanning line 3.

<Fifth Embodiment>
Hereinafter, an organic EL device according to a fifth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 14, the organic EL device of the fifth embodiment has a scanning line corresponding damming portion 605 that performs substantially the same function as the scanning line corresponding damming portion 604 of the fourth embodiment.
However, each of the scanning line corresponding blocking portions 605 is formed so as to straddle three scanning lines 3 (hereinafter referred to as “scanning line group 3G”) as shown in FIG. . In addition, when the scanning line group 3G is taken as a unit and viewed from the end in order, the scanning line corresponding damming portions 605 corresponding to each of the scanning line groups 3G are alternately arranged in steps. It is formed to take a form. It is clear that this is in a parallel relationship with the second embodiment.
Further, as is clear from a comparison between FIG. 14 and FIG. 10, the features related to the reference straight line described in the second embodiment are also valid between the blocking portions 605 of each scanning line group 3. That is, the scanning line corresponding blocking portions 605 of the scanning line groups 3 adjacent to each other overlap each other when viewed along the extending direction of the scanning lines 3. Therefore, it can be considered that the scanning line corresponding blocking portion 605 according to the fifth embodiment also constitutes a so-called labyrinth seal.

  It is apparent that the fifth embodiment also has the effects that are essentially the same as the effects of the fourth embodiment. This is because, also in the fifth embodiment, the scanning line corresponding damming portion 605 is the same as that described above except that the scanning line corresponding damming portion 605 is formed as a set of a plurality of scanning lines 3. This is because it is almost the same as the scanning line corresponding block 604.

In addition, in the fifth embodiment, the effect of preventing the outflow of the planarizing film 80 can be more effectively achieved than in the case of the fourth embodiment. This is because the scanning line corresponding damming portion 605 is formed for each of the scanning line groups 3G including the three scanning lines 3 as a set, and thus formed due to the scanning line corresponding damming portion 605. This is because the levee portion to be formed has a continuous or integrated shape like a wall, at least with respect to the three scanning lines 3.
Even if the scanning line corresponding blocking portion 605 is formed so as to straddle the plurality of scanning lines 3 as described above, the first interlayer insulating film is interposed between the scanning line corresponding blocking portions 605 and the scanning lines 3. 301, both of which are formed as metal wiring thin films located in different layers (see FIG. 12), unlike the first embodiment, etc., an electrical short circuit between them and a plurality of scannings The problem of an electrical short between the lines 3 does not occur.

In addition, as in the fourth and fifth embodiments described above, each of the plurality of scanning lines 3 includes a scanning line corresponding blocking portion (604, 605, etc.) formed as the same layer as the data line 6. In the embodiment, the dam portions 601 and 602 and the auxiliary dam portion 603 according to the first to third embodiments described above may be simultaneously formed as the same layer as the scanning line corresponding dam portions (604 and 605, etc.). Is possible. In FIG. 15, the case where the scanning line corresponding damming portion 605 straddling the three scanning lines 3 of the fifth embodiment and the “step difference” damming portion 602 of the second embodiment are formed simultaneously are exemplified. It is shown.
According to such a so-called matching technique, the outflow of the flattening film 80 associated with each of the plurality of scanning lines 3 is prevented, and the flattening film 80 associated with each of the plurality of data lines 6 is eventually prevented. This also prevents the outflow.

<Sixth Embodiment>
Hereinafter, an organic EL device according to a sixth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 16, the organic EL device of the sixth embodiment has a damming portion 706 that performs substantially the same function as the damming portion 601 of the first embodiment.
This damming portion 706 extends in a direction orthogonal to the extending direction of the data lines 6 and is formed individually according to each data line 6.

However, the blocking portion 706 is not formed as the same layer as the data line 6 as shown in FIG. 16, but is formed as the same layer as the reflective layer 34 shown in FIG. Since the reflective layer 34 is formed on the second interlayer insulating film 302 as shown in FIG. 3 and the like, the damming portion 706 also has the same position. On the other hand, the data line 6 is formed under the second interlayer insulating film 302. Therefore, the damming portion 706 and the data line 6 are electrically insulated.
However, the damming portion 706 is also the same as the damming portion 601 in the first embodiment in the sense that it is formed as the same layer as the reflective layer 34 that is a metal thin film.
In addition, a third interlayer insulating film 303 is formed on such a damming portion 706, and a dike portion 96 resulting from the damming portion 706 is formed on the surface thereof. There is no essential difference between this and the formation of the bank portion 91 by the dam portion 601 in the case of the first embodiment.

  It is apparent that the sixth embodiment also has the effects that are essentially the same as the effects of the first embodiment. This is because, in this sixth embodiment as well, as described above, the damming portion 706 has many common matters such as being formed as the same layer as the metal thin film in comparison with the damming portion 601. Because.

  Moreover, in the sixth embodiment, the effect of preventing the planarization film 80 from flowing out can be more effectively achieved than in the case of the first embodiment described above. This is because the damming portion 706 is formed in a layer different from the data line 6 as described above, and therefore the damming portion 706 is the scanning line corresponding damming portion in the fourth and fifth embodiments. This is because it can be formed so as to straddle a plurality of data lines 6 based on the same concept as in 604 and 605. Thereby, an embankment part like an integral wall can be formed.

<Seventh embodiment>
Hereinafter, an organic EL device according to a seventh embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 17, the organic EL device of the seventh embodiment has a damming portion 607 having a form different from the damming portion 601 of the first embodiment.
The damming portion 607 is formed as the same layer as the data line 6 as compared with the damming portion 601 in the first embodiment, has a portion intersecting with the extending direction of the data line 6, It is the same that they are individually formed according to the data line 6 and that the respective damming portions 602 are not electrically connected to each other.

However, the blocking portion 607 has a wedge shape in plan view as shown in FIG. More specifically, the wedge-shaped damming portion 607 (hereinafter referred to as “wedge-shaped damming portion 607”) has a first oblique side portion that obliquely intersects the data line 6 and the data line 6 with respect to the first oblique side portion. It has a second oblique side that obliquely intersects the data line 6 while having a symmetrical relationship with the one oblique side. One end of each of the first and second oblique sides intersects on the data line 6 and forms a pointed portion of the wedge-shaped damming portion 607. On the other hand, the other ends of the first and second oblique sides extend in directions away from each other.
That is, the wedge-shaped damming portion 607 is formed so that the portion on the opposite side to the pointed portion is directed to the contour line of the planarizing film 80. As a result, the portion on the opposite side functions as an opening for receiving the planarizing film 80 flowing out along the data line 6. The space surrounded by the first oblique side and the second oblique side functions as a receiving part for receiving the planarizing film 80 flowing in through the opening.

  It is apparent that the seventh embodiment also has the effects that are essentially the same as the effects achieved by the first embodiment. This is because, in this seventh embodiment as well, as described above, the wedge-shaped damming portion 607 is formed as the same layer as the data line 6 in comparison with the damming portion 601. Because it has.

  Moreover, in the seventh embodiment, the effect of preventing the outflow of the planarizing film 80 can be more effectively achieved than in the case of the first embodiment. This is because in the seventh embodiment, the wedge-shaped damming portion 607 has a portion that functions as an opening and a receiving portion as described above, so that a certain amount of the flattening film 80 that has flowed out can be retained. Because it can. As a result, even if the flattening film 80 flows out relatively much, the progress can be stopped at the position where the wedge-shaped damming portion 607 is formed.

<Eighth Embodiment>
Hereinafter, an organic EL device according to an eighth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 18, the organic EL device of the eighth embodiment has a damming portion 608 having a form different from the damming portion 601 of the first embodiment.
The damming portion 608 is formed as the same layer as the data line 6 as compared with the damming portion 601 in the first embodiment, has a portion orthogonal to the extending direction of the data line 6, It is the same that they are individually formed according to the data line 6 and that the respective damming portions 602 are not electrically connected to each other.

However, as shown in FIG. 18, the damming portion 608 has a square shape in plan view. More specifically, the dam member 608 (hereinafter referred to as the “Π character dam member 608”) having a cross-shaped shape includes an orthogonal side portion that is a portion orthogonal to the data line 6 and the orthogonal portion. It has two extended side portions extending along the extending direction of the data line 6 from both ends of the side portion.
In addition, as shown in FIG. 18, each of the cross-shaped damming portions 608 is different from each other in the formation position of both cross-shaped damming portions 608 of the adjacent data lines 6. In addition, when each of the data lines 6 is viewed from the end in order, the respective cross-shaped damming portions 602 are formed so as to be alternately arranged in steps. Yes.

In addition, for each of the data lines 6 one by one, the posture of the hook-shaped damming portion 608 is reversed with respect to the vertical direction in the figure. That is, in the leftmost end and the rightmost data line 6 in FIG. 18, the cross-section 608 (hereinafter, also referred to as “first cross-section 608”) extends at the orthogonal side thereof. While being arranged so as to be relatively upward with respect to the side portion in the drawing, the cross-shaped damming portion 608 (hereinafter referred to as “second cross-shaped damming portion 608) of the data line 6 sandwiched therebetween. Is formed such that the extended side portion is relatively on the upper side in the drawing relative to the orthogonal side portion. In this case, the extended side portion of the second cross-shaped damming portion 608 is between the extended side portion of the first cross-shaped damming portion 608 and the data line 6 corresponding to the first cross-shaped damming portion 608. It is positioned to be sandwiched.
In addition, between these 1st and 2nd cross-shaped dam parts 608, the characteristic regarding the reference | standard straight line described in 2nd Embodiment is also applicable similarly.

From the above, it can be considered that the hook-shaped damming portion 608 according to the eighth embodiment also constitutes a so-called labyrinth seal as in the second embodiment.
Further, with respect to the second cross-shaped damming portion 608, the portion between the end portions of the two extended side portions functions as an opening for receiving the planarizing film 80 flowing out along the data line 6. . On the other hand, the space surrounded by the two extended side portions and the orthogonal side portions functions as a receiving portion that receives the planarizing film 80 flowing in through the opening.

  It is obvious that the effect obtained by the eighth embodiment is essentially the same as the effect obtained by the first embodiment. This is because, also in the eighth embodiment, the cross-shaped damming portion 608 is formed as the same layer as the data line 6 in comparison with the damming portion 601 as described above. This is because they have common matters.

  Moreover, in the eighth embodiment, the effect of preventing the outflow of the planarizing film 80 can be more effectively achieved than in the case of the first embodiment. This is because, in the eighth embodiment, the second cross-shaped damming portion 608 has a portion that functions as an opening and a receiving portion as described above. This is because a certain amount can be maintained. As a result, even if the flattening film 80 flows out comparatively much, the progress can be stopped at the position where the hook-shaped damming portion 608 is formed.

  In addition, in the eighth embodiment, since the first and second cross-shaped damming portions 608 described above constitute a labyrinth seal, a flat surface that tends to flow out toward the outside of the element substrate 7. As long as the film 80 does not pass through a relatively complicated path, it cannot flow out beyond the obstacles of the first and second character-shaped dams 608. In short, in the eighth embodiment, the effect of preventing the flattening film 80 from flowing out is very effectively achieved.

<Ninth Embodiment>
Hereinafter, an organic EL device according to a ninth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 19, the organic EL device of the ninth embodiment has a damming portion 609 having a form different from the damming portion 601 of the first embodiment.
This damming portion 609 is formed as the same layer as the data line 6 as compared with the damming portion 601, has a portion intersecting with the extending direction of the data line 6, and corresponds to each data line 6. It is the same that they are individually formed, and that the respective blocking portions 602 are not electrically connected to each other.

However, this damming portion 609 does not have an intersecting portion that bridges two regions separated by the data line 6 like the damming portion 601 of the first embodiment, for example. As shown, the data line 6 itself is shaped by bending (however, this does not mean that the blocking portion 609 according to the ninth embodiment does not have an “intersection”). ("A side" and "E side" can also be considered to correspond to the "intersection").
More specifically, the blocking portion 609 of the ninth embodiment firstly has an A side extending from the part of the data line 6 that is spaced from the contour line of the planarizing film 80 to a certain extent toward the left in the drawing. Part, secondly, the B side extending downward in the figure from the end of the A side, and thirdly, extending from the end of the B side toward the right in the figure, about the A side C side having double length, fourth, D side extending from the end of the C side downward in the figure, and fifth, left side in the figure from the end of the D side And an end portion thereof is an E side portion connected to the data line 6 again.

  Obviously, the ninth embodiment also has the effects that are essentially the same as the effects of the first embodiment. This is because, in this ninth embodiment as well, as described above, the damming portion 609 has many common items such as being formed as the same layer as the data line 6 in contrast to the damming portion 601. Because it has.

As mentioned above, although each embodiment which concerns on this invention was described, the light-emitting device which concerns on this invention is not limited to the form mentioned above, Various deformation | transformation are possible.
(1) For convenience of explanation, each of the above-described embodiments is described as another embodiment having a unique characteristic. However, the present invention is not limited to any one of these other embodiments. Also within the scope are embodiments that appear as one is combined with any other one.
Such an example has already been described with reference to FIG. 15 (a merged form of the second embodiment and the fifth embodiment), but the present invention relates to various other merged forms. Is basically within that range. For example, the wedge-shaped damming portion 607 of the seventh embodiment or the auxiliary damming portion similar to the auxiliary damming portion 603 of the third embodiment is provided behind the scanning line-corresponding damming portion 604 of the fourth embodiment. Forms, merged forms having both the damming portion 601 of the first embodiment and the damming portion 706 of the sixth embodiment, and the like.

(2) In each of the above-described embodiments, an example in which the effect of preventing the outflow of the planarization film 80 along the data line 6 or the scanning line 3 is described, but the present invention is not limited to such a form. .
For example, as described with reference to FIG. 1 and the like, the current supply line 113 is formed in parallel with the data line 6. The current supply line 113 also flows out of the planarization film 80 as described above. Naturally, it is possible that the phenomenon to promote will occur. In such a case, the outflow of the planarizing film 80 along the current supply line 113 can be prevented by forming a “damming portion” for the current supply line 113 as well.
In the first embodiment, an example in which the blocking portion 601 is formed in the area AEL shown in FIG. 1 has been described. However, since the data line 6 is also connected to the precharge circuit 106A, There is a possibility that the outflow phenomenon of the planarization film 80 as described above may occur between the two. Therefore, it may be considered to form a “damming portion” for the portion.

(3) In the sixth embodiment, a “damming portion” is described in which the blocking portion 706 is formed as the same layer as the reflective layer 34 and is not formed as the same layer of either the data line 6 or the scanning line 3. However, this concept can be similarly applied to other various “metal films”.
For example, although not shown, an auxiliary electrode may be formed on the counter electrode 5 shown in FIG. 3 or the like for the purpose of stabilizing the potential of the counter electrode 5 (the auxiliary electrode is a counter electrode). Corresponding to the electrode 5 being made from a material having a relatively high resistance value such as ITO, it is made by a material having a relatively lower resistance value).
Such an auxiliary electrode is also a “metal film”, and therefore, the “damming portion” can be formed as the same layer as the auxiliary electrode.

(4) In the above embodiments, particularly in FIG. 15 described above, the scanning line corresponding damming portion 605 of the fifth embodiment and the damming portion 602 of the second embodiment are formed at the same time. This is based on the premise that the scanning lines 3 (all) and the data lines 6 (all) are formed in different layers. More generally, however, the scan line and the data line need not all be formed in different layers. In other words, it is essential to provide an interlayer insulating film between the scanning line and the data line when the scanning line and the data line intersect in order to prevent a short circuit between them. Both the line and the data line may be formed in the same layer. This is particularly true in the peripheral area of the image display area 7a.
In this case, the mode of forming the blocking portion for the scanning line and the data line formed in the same layer can be suitably selected from the above embodiments, for example. For example, the damming portion 601 of the first embodiment is formed for each of these scanning lines and data lines.
In this case, it can be understood that both the “scan line” and the “data line” have relevance to the “first wiring film” in the present invention.

(5) Although the light emitting device according to each of the embodiments described above is a top emission type, the light emitting device according to the present invention may be a bottom emission type. Alternatively, it may be a dual emission type.
(6) The light emitting device according to each of the embodiments described above is an organic EL device, but the light emitting device according to the present invention may be an inorganic EL device.
