[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electroluminescence display device such as an organic electroluminescence display device, and more particularly to a display device that emits light from above an element formed on a substrate.
[0002]
[Prior art]
At present, a display device using an electroluminescence (hereinafter referred to as EL) element formed using an organic light-emitting material or an inorganic light-emitting material as a light-emitting molecule has attracted attention. In particular, organic light-emitting materials are expected as next-generation color displays because of their many types of luminescent colors.
[0003]
FIG. 4 shows a circuit configuration per pixel of an active matrix organic EL display device. As shown in the drawing, in the active matrix organic EL display device, a plurality of gate lines GL extend in the row direction, and a plurality of data lines DL and power supply lines VL extend in the column direction on the substrate. The vicinity of the area surrounded by the data line DL, the power supply line PvL, and the gate line GL is an area corresponding to one pixel. In this one pixel area, the organic EL element 3, the switching TFT (first TFT) 1, and the EL An element driving TFT (second TFT) 2 and a storage capacitor Csc are provided.
[0004]
The first TFT 1 is connected to the gate line VL and the data line DL, and is turned on when the gate electrode receives a gate signal (selection signal). At this time, the electric charge corresponding to the display data signal supplied to the data line DL is held in the holding capacitor Csc connected between the first TFT 1 and the second TFT 2. The gate electrode of the second TFT 2 is applied with a voltage (voltage corresponding to the data signal) corresponding to the electric charge held by the storage capacitor Csc, and the second TFT 2 supplies the current corresponding to the gate voltage from the power supply line PvL. Supply to the EL element 3.
[0005]
FIG. 5 shows a schematic cross-sectional configuration in the vicinity of the organic EL element 3 and the second TFT of the organic EL display device. Note that the first TFT not shown in FIG. 5 has substantially the same structure as the second TFT.
[0006]
The active layer 12 of the second TFT is formed on the transparent substrate 10 such as glass, and the gate insulating film 14 covers this, and the source region of the first TFT shown in FIG. A gate electrode 20 electrically connected to the lower electrode is formed. An interlayer insulating film 16 is formed on the upper layer of the gate electrode 20, and contact holes penetrating the interlayer insulating film 16 and the gate insulating film 14 are formed at positions corresponding to the source and drain regions of the active layer. The source region 12s of the second TFT is connected to the power supply line PvL that also serves as the source electrode through this contact hole, and the drain region 12d is connected to the drain electrode through the contact hole. Further, a first planarization insulating layer 18 is formed on the entire surface of the substrate covering the power supply line PvL and the drain electrode, and the organic EL element 3 is formed on the first planarization insulating layer 18.
[0007]
The organic EL element 3 includes a transparent electrode (anode) 50 made of ITO (Indium Tin Oxide) and the like, and a metal electrode (cathode) 60 formed in common with the light emitting element layer and each pixel. 1 is laminated on the planarization insulating layer 18 in this order. The transparent electrode 50 is connected to the drain electrode of the second TFT through a contact hole formed in the first planarization insulating layer 18. The light emitting element layer is configured, for example, by laminating a hole transport layer 52, a light emitting layer 54, and an electron transport layer 56 in this order.
[0008]
The element substrate is configured by forming TFTs, storage capacitors, organic EL elements, and necessary wirings that constitute each pixel. In order to protect each element on the element substrate and prevent deterioration of the organic material contained in the light emitting element layer due to moisture, a metal sealing member 90 is conventionally provided on the element forming surface side of the light emitting element layer. ing. The sealing member 90 is bonded to the element substrate around the pixel region of the element substrate, and dry nitrogen is sealed in a sealing space 92 between the sealing member 90 and the element substrate.
[0009]
The organic EL element 3 is supplied with current corresponding to the data signal voltage from the power supply line PvL to the anode 50 via the second TFT. As a result, holes are injected from the anode 50 into the light emitting element layer, electrons are injected from the cathode 60, and the injected holes and electrons move through the light emitting element layer and recombine at the light emitting layer 54. The light emitting molecules in the light emitting layer are excited by the recombination energy. Then, when returning to the ground state, light is emitted from the light emitting layer 54.
[0010]
[Problems to be solved by the invention]
In the conventional organic EL element 3, a metal material having a small work function such as Al is used as the cathode 60 and is opaque. On the other hand, the anode 50 is transparent because ITO or the like is used as a conductive material having a high work function capable of injecting holes into the light emitting element layer as described above. Therefore, the light from the light emitting layer 54 is not emitted from the cathode 60 but emitted to the outside through the transparent substrate 10 from the anode 50 side.
[0011]
Here, since the wiring and the TFT formation region block light from the light emitting layer, when the light is emitted from the transparent electrode 10 side, the wiring and TFT formation region restricts the light emitting region of each pixel. It will be. Therefore, there is a problem that the light emission area of each pixel, that is, the aperture ratio, which is the ratio of the light emission region per pixel, is restricted by the TFT formation area.
[0012]
Therefore, research on a configuration capable of emitting light from the cathode side of the organic EL element 3 shown in FIG. 5 has begun.
[0013]
However, in such a configuration in which light is emitted from the cathode side, light is not blocked by wiring or TFT between adjacent pixels, so that the problem of light leakage between adjacent pixels is more remarkable. It is thought that it becomes. In particular, since the organic EL element is a self-emitting element close to a point light source that emits light in all directions, it is necessary to prevent leakage of emitted light between adjacent pixels.
[0014]
In order to solve the above problems, an object of the present invention is to realize an EL display device having a high aperture ratio and capable of preventing light leakage between adjacent pixels.
[0015]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an organic electroluminescence display device comprising a light emitting element layer including at least a light emitting layer between a first electrode and a second electrode on a substrate, and formed on the substrate side. An element substrate on which a plurality of light emitting pixels each having an organic electroluminescence element that emits light from the light emitting layer is disposed from the second electrode side formed above the first electrode, and an element forming surface side of the element substrate And a transparent sealing member disposed at a predetermined distance. Further, the second electrode is provided in common to each light emitting pixel, and a light shielding member that shields each light emitting pixel from other light emitting pixels is provided in the gap between the second electrode and the transparent sealing member. It is characterized by.
[0016]
Thus, by adopting an element configuration in which emitted light can be emitted from the second electrode side positioned on the upper side of the element substrate, and further adopting a transparent sealing member as the element sealing substrate, the transparent sealing member is externally provided. The light from the light-emitting layer can be efficiently emitted to the outside without being restricted by the wiring and switch elements for controlling the EL elements for each pixel, thereby improving the aperture ratio. Can be planned. Further, by providing a light-shielding member that shields between pixels in the gap between the substrate and the transparent sealing member disposed on the element forming surface side of the substrate, the light emitted from the second electrode side is separated by the light-shielding member. Can be prevented from being emitted from the pixel region. Therefore, it is possible to prevent bleeding between pixels of the display image and to prevent color mixing in the color display device.
[0017]
In another aspect of the present invention, in the organic EL display device, the transparent sealing member includes a color element at a position corresponding to each light emitting pixel on the surface facing the organic electroluminescence element, and the light shielding member includes: The color element is provided so as to project toward the substrate in a gap with another color element.
[0018]
The set gap between the element substrate and the transparent sealing member and the color elements (color filter, color conversion filter, etc.) formed on the transparent sealing member are the thicknesses of the EL elements formed on the element substrate and the switch elements thereof. This is a very large value. Therefore, there is a considerable difference in the accuracy and characteristics of each manufacturing apparatus between the element layer and the light shielding member and the color element. If the light shielding member and the color element are formed on the transparent sealing member side, the element substrate and the transparent element are transparent. The sealing substrate can be manufactured in parallel on different optimal manufacturing lines, which is advantageous in terms of manufacturing efficiency. In addition, when the light shielding member and the color element are formed on the element substrate side, these are formed on the second electrode. However, in the organic EL element or the like, the chemical solution resistance of the light emitting element layer is low or moisture is absorbed. Since there is a property such as deterioration, it is often desirable that the light-emitting element layer is not exposed to many film forming steps after the light-emitting element layer is formed. Even in such a case, in the present invention, since the light shielding member and the color element are formed on a transparent sealing member that can be manufactured separately from the element substrate, the EL element is not affected by the light shielding member or the color element. The manufacturing process is not adversely affected.
[0019]
In another aspect of the present invention, in the organic EL display device, the light shielding member has a black surface at least facing the transparent sealing member. As described above, the EL display device of the present invention is configured to emit light emitted from the EL element to the outside from the transparent sealing member side, and this transparent sealing member side serves as an observation surface. Therefore, the black matrix is arranged at each position between the light emitting pixels because the upper surface of the light shielding member (the surface facing the transparent sealing member) that is visible through the transparent sealing member from this observation surface is black. Will be. Therefore, it becomes easy to clearly express the difference in emission luminance and emission color between adjacent pixels, which contributes to further improvement in display contrast.
[0020]
In another aspect of the present invention, in the organic EL display device, at least a part of the side surface of the light shielding member has a reflection function.
[0021]
If the side surface has a reflection function, the light emitted from the light emitting layer through the second electrode is reflected by this reflecting member, and the light from the light emitting layer is emitted to the outside as light of the pixel without any loss. Can do.
[0022]
In another aspect of the present invention, in the organic EL display device, the light shielding member is formed so as to surround each light emitting pixel region.
[0023]
As described above, when the light emitting layer functions in the same manner as a point light source, it is possible to prevent light from leaking to adjacent pixels in all directions, particularly by surrounding each light emitting pixel region.
[0024]
In another aspect of the present invention, in the organic EL display device, switching elements for individually controlling each light emitting pixel are formed between the substrate and the organic EL element .
[0025]
Thus, if it is what is called an active matrix type display device provided with the switch element which controls a light emitting pixel individually, the display quality of each pixel is high. Further, even when the switch element or the like is formed on the element substrate as described above, the light from the light emitting layer is emitted from the second electrode side located opposite to the position where the switch element is formed, so that the aperture ratio is reduced. And display with high brightness and high quality.
[0026]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.
[0027]
FIG. 1 shows a cross-sectional structure of an EL display device according to an embodiment of the present invention. In this embodiment, this EL display device is an active matrix organic EL display device in which each pixel includes an organic EL element using an organic material. The circuit configuration of each pixel is the same as the equivalent circuit shown in FIG. 4 described above, and one pixel includes the organic EL element 3, first and second TFTs for controlling the organic EL element 3, and a storage capacitor Csc. In FIG. 1, the element configuration formed below the first planarization insulating layer 18 can adopt the same configuration as the conventional one. For example, the second TFT is the same as that shown in FIG. Has the same configuration as the second TFT. In FIG. 1, parts common to those in FIG. Of course, different structures such as a material of each film and a top gate structure of the TFT may be adopted as a bottom gate structure.
[0028]
As shown in FIG. 1, on the first planarization insulating layer 18, a first electrode 40 having an individual pattern is formed for each pixel and connected to the drain electrode of the second TFT through a contact hole. Yes. A light emitting element layer 30 is laminated on the first electrode 40, and a second electrode 42 having a multilayer structure common to each pixel is formed thereon. The light emitting element layer 30 includes a light emitting layer containing at least a light emitting molecule. In the present embodiment, as an example, the light emitting element layer 30 has a three-layer structure of a hole transport layer 32, a light emitting layer 34, and an electron transport layer 36. FIG. 1 shows an example in which the hole transport layer 32 and the electron transport layer 36 are formed in common for all the pixels, and the light emitting layer 34 is formed independently for each pixel and in a pattern slightly larger than the first electrode 40. Yes. In the case of a color display device, the light emitting layer 34 is made of a different desired light emitting material depending on the color of light to be emitted.
[0029]
In addition, a second planarization insulating layer 26 that covers the edge of the first electrode 40 is formed in a gap portion between the first electrodes 40. Since the light emitting element layer 30 is actually very thin, the first and second electrodes 40 and 42 facing each other with the light emitting element layer 30 interposed therebetween are near the edge of the first electrode 40 by the second planarization insulating layer 26. To prevent short circuit.
[0030]
What is characteristic in the present embodiment is that the second electrode 42 formed in an upper layer than the first electrode 40 is light transmissive. As in FIG. 5, the first electrode 40 constitutes an anode, and a transparent conductive material such as ITO having a large work function capable of injecting holes into the hole transport layer 32 of the light emitting element layer is used. Yes. Since the second electrode 42 constitutes a cathode, it is necessary to use a material having a small work function and easy electron injection. However, on the other hand, the light transmission function must be exhibited, and the same ITO as the anode is considered as a material. However, a metal oxide such as ITO does not have a high electron injection capability. Therefore, in the present embodiment, the second electrode 42 has a laminated structure of the metal layer 44 and the transparent conductive layer 46, and the metal layer 44 is provided at a position in contact with the interface with the electron transport layer 36. A metal having a small work function capable of efficiently injecting electrons into the electron transport layer 36 of the element layer 30 is used, and these metal materials are usually light-shielding, but are formed as thin films capable of transmitting light. is doing. For example, Al, Au, Ag, or the like is used for the metal layer 44. A transparent conductive layer 46 such as ITO is formed on the upper layer of the metal layer 44, and the cathode is constituted by these two layers. Note that the second electrode (cathode) 42 can also be configured using a light-shielding metal material. In this case, the second electrode 42 has a plurality of openings formed per pixel region. What is necessary is just to employ | adopt the structure which is.
[0031]
As described above, by injecting electrons from the second electrode 42 having a stacked structure into the light emitting element layer 30 and injecting holes from the first electrode 40 into the light emitting element layer 30, the organic EL element 3 of the present embodiment In the light emitting layer, light having a color caused by light emitting molecules is emitted, and the light is emitted through the light-transmissive second electrode 42.
[0032]
Although not explicitly shown in FIG. 1, when a transparent electrode is adopted as the first electrode (anode) 40, the first electrode 40 is not transmitted through the transparent electrode so that light does not leak to the substrate 10 side. A reflective layer is preferably provided on the lower layer, the outer surface of the substrate 10 or the like.
[0033]
The element substrate 100 is configured by forming the organic EL element 3, the first and second TFTs, the storage capacitor Csc, wiring necessary for driving them, and the like. In the present embodiment, the transparent sealing member 200 is disposed opposite to the element formation surface side of the element substrate 100 in order to protect the element and to emit light that passes through the second electrode 42 to the outside. Further, although not shown in FIG. 1, the transparent sealing member 200 is bonded to the element substrate 100 and the pixel portion peripheral region using the element substrate 100 and UV curable resin. A transparent substrate 80 such as glass is used for the transparent sealing member 200 so that light emitted through the second electrode 42 can be transmitted.
[0034]
[Shading member]
The characteristic light shielding member 70 in the present embodiment will be described. The light shielding member 70 is disposed in a gap (sealing space) 84 between the element formation surface of the element substrate 100 and the transparent sealing member 200 and shields the light emitting pixels from other light emitting pixels. The light shielding member 70 may exist between the element substrate 100 and the transparent sealing member 200 by any means as long as the light shielding member 70 is disposed at a position that shields light between pixels. In this embodiment, the light shielding member 70 is transparent. On the surface of the substrate 80 facing the element, it is formed so as to protrude toward the element substrate 100. FIG. 2 shows a configuration when the light shielding wall 70 formed on the transparent substrate 80 and a color element 82 described later are observed from the element substrate side. 3 is a transmission diagram when the transparent sealing member 200 is viewed from the observation surface (the upper surface in FIG. 1) of the display device.
[0035]
For the light shielding member 70, for example, a black resin material can be used. In this case, the black resin material is applied or printed on the transparent substrate 80 to a thickness approximately equal to the distance between the sealing member 200 and the second electrode 42 of the element substrate 100. Then, by hardening this and removing the pixel corresponding region by etching, a wall having a desired pattern, in particular, a wall surrounding the light emitting pixel region as shown in FIGS. 1 and 2 can be easily formed. In the following description, the light shielding member 70 will be described by taking a light shielding wall as an example. Of course, the light shielding pixel 70 may not be configured to completely surround the light emitting pixel region, and is formed in a wall shape or a column shape only in a region close to the adjacent pixel. May be. However, the light shielding function and the light efficiency are improved when the pattern completely surrounds the light emitting pixel region. As will be described later, when the color element 82 is formed in each light emitting pixel corresponding region, either the color element 82 or the light shielding wall 70 may be formed first.
[0036]
The distance between the transparent sealing member 200 and the second electrode 42 of the element substrate 100 is about 20 μm or less, and the light shielding wall 70 is formed with a thickness (height) of about 2 μm to 10 μm, for example, according to this distance. The By setting the light shielding wall 70 to a height substantially equal to the distance between the transparent sealing member 200 and the second electrode 42 of the element substrate, the light emitted through the second electrode 42 can reach the adjacent pixel region. It can be surely prevented. In addition, by setting the light shielding wall 70 to a height substantially equal to the distance between the sealing member 200 and the second electrode 42, the light shielding wall 70 can also function as a spacer therebetween. By functioning as a spacer, it is possible to prevent the sealing member 200 from being bent due to external pressure and coming into contact with the second electrode 42, improving the strength as a display device, and preventing damage to internal elements. Is possible.
[0037]
Here, the formation of the light shielding wall 70 on the transparent sealing member 200 is superior to the formation of the element substrate 100 in terms of efficiency of the manufacturing process. In FIG. 1, for ease of expression, the scales are illustrated at approximately the same scale, but actually, the height of the light shielding wall 70, that is, the gap between the second electrode 42 of the element substrate and the transparent sealing member 200 is illustrated. Is one digit or more larger than the total thickness of the organic EL element formed on the element substrate 100 and its switch element. Further, as will be described later, the color elements are also very thick compared to organic EL elements and the like. For this reason, there is a considerable difference in the accuracy and characteristics of each manufacturing apparatus between each element on the element substrate side, the light shielding wall, and the color element. Therefore, the light shielding wall 70 and the color element 82 that need to be thickened are formed on the transparent sealing member side, so that the element substrate 100 and the transparent sealing member 200 can be manufactured in parallel on separate lines. Further, the light emitting element layer 30 of the organic EL element 3 may deteriorate due to moisture absorption or have low chemical resistance. However, if the light shielding wall 70 is formed on the transparent sealing member 200 side, Only the second electrode formation step is necessary above. Therefore, the problem of deterioration of the light emitting element layer 30 due to a subsequent process does not occur.
[0038]
Further, it is preferable that at least the side surface (72) of the light shielding wall 70 has a reflection function, that is, has a reflection side surface. FIG. 1 shows a configuration in which a reflective layer 72 is separately formed on the side surface of the light shielding wall made of a black resin material. Of course, if the light shielding wall 70 itself is a reflective material such as metal, it is not necessary to provide a separate reflective member on the wall surface. In any case, since the side surface (wall surface) of the light shielding wall 70 has a reflection function, it is generated in the light emitting layer 34 of the organic EL element as shown in FIG. 1, and is transmitted through the second electrode 42 and emitted. Of the light, the light traveling toward the side surface 72 of the light shielding wall 70 is reflected without being absorbed by the side surface 72 and is emitted from the transparent sealing member 200 as light from the pixel region. Therefore, the light use efficiency from the light emitting layer 34 can be increased.
[0039]
Next, it is preferable that at least the facing surface 74 of the light shielding wall 70 facing the transparent substrate 80 is black. If the light shielding wall 70 is formed using a black resin material or the like as described above, it can be easily realized. Further, even when a black material is not particularly used as the light shielding wall 70 material, it can be coped with by forming a black layer on the surface (contact surface) 74 facing the transparent substrate 80 as shown in FIG. In any case, when viewed from the observation surface side as shown in FIG. 3, the surface of the light shielding wall 70 on the transparent substrate 80 side functions as a black matrix for separating each pixel, and can contribute to improvement in contrast.
[0040]
In addition, although the case where the light shielding wall 70 was formed in the transparent sealing member 200 side was demonstrated above, the structure formed also in the element substrate 100 side is employable. For example, the light shielding wall 70 is projected toward the transparent sealing member 200 in the formation region of the second planarization insulating layer 26. In such a configuration, the second electrode 42 is separated by the light shielding wall 70 between pixels adjacent in the row or column direction, and extends in a strip shape along the light shielding wall 70 in the row or column direction. A common voltage may be applied to each other around the region.
[0041]
[Color elements]
As shown in FIGS. 1 and 2, in the present embodiment, color elements 82 can be provided at positions corresponding to the respective light emitting pixels of the transparent sealing member 200. The color element 82 may employ a color conversion filter layer that converts incident light into light of a desired wavelength, in addition to color filter layers such as R, G, and B when performing color display. Here, in the organic EL element, since the light emitting element layer has a relatively high resistance, basically, only the portion where the first electrode 40 and the second electrode 42 face each other with the light emitting element layer interposed therebetween emits light. Therefore, the light emitting region in the present embodiment is substantially equal to the pattern of the first electrode 40 formed individually for each pixel. In such a case, the color element formed on the transparent sealing member can be more reliably prevented from leaking light to the adjacent pixels by making the pattern slightly larger than the light emitting area of the element.
[0042]
In addition, it is necessary to configure the light emitting element layer using a different material for each normal emission color. When these color filters, color conversion filter layers, and the like are formed on the element facing surface side of the sealing member 200, the light emitting element layer is used. For example, 30 may emit white light in all pixels. Further, in the case where the light emitting element layer 30 is the same for all pixels, the light emitting element layer 30 is not limited to white light emission, and may be other monochromatic light emission such as R, G, and B. In particular, when a color conversion filter layer is employed as a color element, any other light emitting element light emitting element layer may be employed as long as the light emission color can be converted into a desired color by this filter layer. Of course, in each of the R, G, and B pixels, the light emitting element layer 30 emits the corresponding R, G, and B, respectively, and the color purity of each color is increased by the correspondingly arranged color elements. May be.
[0043]
In addition, the color element 82 is not an essential component for the monochromatic display device. Even in the case of such a monochromatic display device, it is possible to obtain an effect of preventing light leakage between the pixels because the above-described light shielding wall 70 exists between the pixels.
[0044]
【The invention's effect】
As described above, according to the present invention, it is possible to emit emitted light from the second electrode side located on the upper side of the EL element substrate, and adopting the transparent member for element sealing, the transparent sealing member Light can be emitted from the outside. Therefore, the light from the light emitting layer can be efficiently emitted to the outside without being restricted by the wiring or the switch element for controlling the EL element, and the aperture ratio can be improved.
[0045]
Furthermore, since it has a light-shielding member that shields between pixels in the gap between the second electrode of the element substrate and the transparent substrate for sealing, the light emitted from the second electrode side is prevented from reaching other pixel regions, It is possible to prevent bleeding between pixels of a display image and to prevent color mixing in a color display device. Further, the light emitted through the second electrode side can be emitted to the outside with little loss.
