Abstract

PROBLEM TO BE SOLVED: To solve such a problem that light leaks from an adjoining element due to position gap or the thickness of a lenticular lens sheet itself in a configuration of a high definition organic EL device capable of displaying the directivity, where a color filter substrate or a lenticular lens sheet is bonded to an element substrate.SOLUTION: The organic EL device 1 comprises: on a substrate body 20, an anode 10 as a first electrode; a partition wall 13 having an opening corresponding to the position where the anode 10 is formed; a function layer 12 arranged at least in the opening; a cathode 11 as a second electrode covering the partition wall 13 and the function layer 12; a single layer or a multilayer sealing layer F covering the cathode 11; a color filter 25 arranged on the sealing layer F while overlapping the opening in the plan view; and a lenticular lens 27 arranged on the color filter 25. Since the position gap of the color filter 25 and the lenticular lens 27 for the opening is small, and the optical path length from the function layer 12 to the lenticular lens 27 is short, leakage light from an adjoining pixel is small.

Description

  The present invention relates to an organic EL device and an electronic apparatus including the organic EL device.

  2. Description of the Related Art Conventionally, as one electro-optical device, a display device that can display a different image for each viewing direction (hereinafter referred to as directional display) when viewed from a plurality of directions is known. As such a display device, a lenticular lens corresponding to parallax image information for the left eye and right eye displayed on the display unit, and a position adjusting unit capable of adjusting the position of the lenticular lens with respect to the display unit are provided. There is one in which a filter is attached to a frame portion and the frame portion is attached to the display portion in a removable state (see, for example, Patent Document 1).

JP 2005-173034 A

  However, the lenticular lens is generally formed on the surface of a sheet-like substrate having a thickness of about several hundred microns to several millimeters, and this is attached to the display unit. The display unit includes, for example, a plurality of pixels and a color filter provided for each pixel. Since the directional display can be obtained by matching the position of the color filter corresponding to the pixel and the lenticular lens, the accuracy of alignment between the color filter and the lenticular lens is improved as the resolution of the display device is increased. There was a problem that became difficult. For example, when a lenticular lens sheet having a substrate thickness of 500 microns is bonded to a display portion having a pixel pitch of 15 microns, the color filter and the lenticular lens on the lenticular lens sheet are optically enlarged to have the same coverage. It is very difficult to align with a field of view within the depth of field.

  Furthermore, when the substrate thickness of the lenticular lens sheet is several times thicker than the pixel pitch, the light emitted from the color filter corresponding to the pixel enters the adjacent lenticular lens. There is a problem in that the resolution of the directional display is deteriorated.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

Application Example 1 An organic EL device according to this application example has a function in which a first electrode, a partition wall having an opening corresponding to a position where the first electrode is formed, and at least the opening are arranged on a substrate. A layer, a second electrode that covers the partition wall and the functional layer, a single-layer or multilayer sealing layer that covers the second electrode, and the opening is disposed on the sealing layer so as to overlap with the opening. A color filter and a lenticular lens disposed on the color filter;
It is characterized by having.

  According to this application example, since the lenticular lens is disposed on the color filter, it is not necessary to align the color filter and the lenticular lens through the base material forming the lenticular lens sheet. The magnifying means makes it possible to capture the field of view within the same depth of field, and the positioning of both is simple. In addition, the distance between the color filter and the lenticular lens is shortened, and the rate at which light emitted from the color filter in a substantially oblique direction enters the adjacent lenticular lens can be reduced, thereby suppressing deterioration in resolution of directional display. It is possible to provide an organic EL device that can

  Application Example 2 In the organic EL device according to the application example described above, an organic planarization layer is provided between the color filter and the lenticular lens.

  According to this application example, since the organic flattening layer is provided between the color filter and the lenticular lens, the lenticular lens can be formed on the flattened structure that absorbs the level difference caused by the presence or absence of the color filter. Thereby, it is possible to realize an organic EL device including a lenticular lens having a better cylindrical shape with less influence of the color filter shape.

  Application Example 4 In the organic EL device according to the application example, the first pixel and the second pixel have the color filters of different colors, and the lenticular lens is adjacent to the first pixel. It is characterized by being arranged between the approximate center of the second pixel and the approximate center of the second pixel.

  According to this application example, it is possible to display an image of one pixel by sorting it in the left and right directions by the lenticular lens. Therefore, the left-eye and right-eye images are alternately displayed, and in synchronization with the alternate image display, only the right-eye image reaches the right eye and only the left-eye image reaches the left eye. In this way, it is possible to provide a parallax image without reducing the resolution of the display device.

  Application Example 5 In the organic EL device according to the application example described above, when the stacked structure from the first electrode to the color filter is a pixel, the plurality of pixels are red pixels each including a red color filter. And at least a green pixel provided with a green color filter and a blue pixel provided with a blue color filter, a color pixel comprising a set of the red pixel, the green pixel and the blue pixel, A first color pixel that displays one image and a second color pixel that displays a second image; and the lenticular lens includes the first color pixel and the second color pixel that are adjacent to each other. It is characterized by being arranged so as to cover the color pixels.

  According to this application example, since the lenticular lens is provided so as to cover the color pixels that display two different images, when the color pixels are configured with, for example, three colors of red, green, and blue, compared to Application Example 3. A lenticular lens that covers the pixel with a width of 3 times is formed, and even if the pixel becomes high definition, the lenticular lens does not need to be refined to the same resolution, so it can be formed relatively easily It becomes.

(First embodiment)
The organic EL device according to the first embodiment of the present invention will be described below with reference to FIGS. In all the drawings below, the film thicknesses and dimensional ratios of the constituent elements are appropriately changed in order to make the drawings easy to see.

  The organic EL device in the present invention is a so-called “top emission type” organic EL device. In the top emission method, light is extracted from the opposite substrate side instead of the substrate side where the organic EL elements are arranged, so the emission area is not affected by the size of various circuits arranged on the element substrate, and a wide emission area is secured. it can. Therefore, luminance can be secured while suppressing voltage and current, and the lifetime of the light-emitting element can be maintained long.

  As shown in FIGS. 1 and 2, the organic EL device 1 according to the present embodiment includes an element substrate 20 </ b> A in which a plurality of light emitting elements 21 are arranged on a substrate body 20, and a protective substrate 30. The element substrate 20A is provided with a sealing layer F in which each layer of the electrode protection layer 17, the organic buffer layer 18, and the gas barrier layer 19 formed by covering and laminating the plurality of light emitting elements 21 is further laminated. A color filter layer 25 and an organic planarization layer 26 are formed on the stop layer F, and a lenticular lens 27 is provided thereon. A protective substrate 30 is bonded to the element substrate 20A through a seal layer 33.

(Element board)
As the substrate body 20 provided in the element substrate 20A, either a transparent substrate or an opaque substrate can be used. Examples of opaque substrates include ceramics such as alumina, metal sheets such as stainless steel that have been subjected to insulation treatment such as surface oxidation, thermosetting resins and thermoplastic resins, and films thereof (plastic films). It is done. Examples of the transparent substrate include inorganic materials such as glass and silicon nitride, organic polymers (resins) such as acrylic resins and polycarbonate resins, and materials having optical transparency such as composite materials thereof.

  Formed on the substrate body 20 is an element layer 16 including driving elements such as driving TFTs, wiring such as scanning lines and common lines, and an inorganic or organic insulating film that electrically insulates them. ing. Various wirings and driving elements can be appropriately formed by patterning by photolithography and then etching, and the insulating film can be appropriately formed by a generally known method such as vapor deposition or sputtering. The insulating film of the element layer 16 is made of, for example, silicon oxynitride.

  On the element layer 16, a metal reflector 15 that reflects the light emitted from the light emitting element 21 toward the protective substrate 30 is formed. The metal reflector 15 is made of, for example, a metal such as aluminum or copper, and has a property of reflecting light. In this embodiment, it is made of aluminum. The metal reflecting plate 15 is disposed so as to overlap the light emitting element 21 in a plane between a light emitting element 21 described later and the substrate body 20.

  A light emitting element 21 is disposed in a region overlapping the metal reflector 15 in a plane, and a partition wall 13 is formed between adjacent light emitting elements 21 and between the light emitting element 21 and the end of the substrate body 20. ing. In other words, the light emitting element 21 is partitioned by the partition wall 13. The partition wall 13 is formed of an insulating resin material. Since the formation method uses photolithography, for example, a photosensitive acrylic resin or a cyclic olefin resin is used as the material. The partition wall 13 has a function of preventing “light leakage” in which light is emitted obliquely from the light emitting element 21 and allowing light to enter the corresponding color filter 25. Specifically, in order to prevent light leakage from the adjacent light emitting elements 21, the partition wall 13 has a height of about 2 μm from the surface of the element layer 16.

  The light emitting element 21 is configured by sandwiching a functional layer 12 including a light emitting layer between an anode 10 as a first electrode and a cathode 11 as a second electrode, and is provided on a planarization layer surrounded by a partition wall 13. It has been. The thickness of the light emitting element 21 is about 500 nm. The top surface of the light emitting element 21 and the top of the partition wall 13 have a thickness (height) difference of 1 μm or more, and in the region where the plurality of light emitting elements 21 are arranged, an uneven shape having undulations of 1 μm or more is formed. It is formed continuously.

  The anode 10 is formed on the element layer 16 and connected to the driving TFT provided in the element substrate 20A. A material having a high hole injection effect having a work function of 5 eV or more is preferably used for the anode 10. Examples of such a material having a high hole injection effect include metal oxides such as ITO (Indium Thin Oxide). In this embodiment, ITO is used as the anode. Note that the anode 10 is not necessarily required to have optical transparency, and may be a metal electrode that reflects light such as aluminum. In that case, since the anode 10 reflects light, the metal reflector 15 described above may not be provided.

  The light emitting layer included in the functional layer 12 employs a white light emitting layer that emits white light. In this embodiment, the white light emitting layer is formed using a low molecular weight light emitting material by a vacuum deposition method. As a white light emitting material, white light is emitted by simultaneously emitting a layer obtained by doping an anthracene-based dopant (blue) and a layer doped with a rubrene-based dopant (yellow) in a stricylamine-based light-emitting layer. The light emitting material which implement | achieves can be mentioned. Although a low molecular light emitting material is used here, a light emitting layer may be formed using a polymer light emitting material. It is also possible to change the configuration of each layer to have a three-layer structure in which white light is extracted by simultaneously emitting red, green, and blue colors. The light emitting layer may include a red light emitting layer that emits red light, a green light emitting layer that emits green light, and a blue light emitting layer that emits blue light.

  In addition, a triarylamine multimer (ATP) layer (hole injection layer), a triphenyldiamine derivative (TPD) layer (hole transport layer), a light emitting layer and a cathode 11 are provided between the anode 10 and the light emitting layer. It is preferable that an aluminum quinolinol (Alq3) layer (electron injection layer) and LiF (electron injection buffer layer) are respectively formed between the electrodes to facilitate injection of electrons and holes from each electrode.

  The cathode 11 covers the surfaces of the functional layer 12 and the partition wall 13 and extends to at least the top of the partition wall 13 disposed on the outermost side (the side closer to the outer periphery of the element substrate 20A). Yes. As a material for forming the cathode 11, a material having a large electron injection effect (a work function of 4 eV or less) is preferably used. For example, calcium, magnesium, sodium, lithium metal, or a metal compound thereof. Examples of the metal compound include metal fluorides such as calcium fluoride, metal oxides such as lithium oxide, and organometallic complexes such as acetylacetonato calcium. When these materials are used, the cathode 11 is formed using a high-density plasma film forming method such as a vacuum deposition method for a metal material and an ECR plasma sputtering method, an ion plating method, or a counter target sputtering method for a metal compound. Can do.

  In addition, these materials alone have high electrical resistance and do not function as electrodes, so patterning a metal layer such as aluminum, gold, silver, or copper to avoid the light emitting part, or transparent metals such as ITO or tin oxide You may use it as a laminated body in combination with an oxide conductive layer. In the present embodiment, a magnesium-silver alloy (MgAg) is used by adjusting the film thickness to 20 nm or less so that transparency can be obtained. The thickness of the cathode 11 is about 10 nm.

  Also, a cathode wiring is formed in the vicinity of the outer periphery on the element substrate 20A and in which the planarizing layer of the element layer 16 is not formed, and the cathode wiring and the cathode 11 are connected by the auxiliary cathode wiring to be conductive. Yes.

  The cathode wiring is formed for the purpose of energizing the cathode 11 to a power source (not shown), and is mainly provided near the outer periphery of the element substrate 20A. As a material for forming the cathode wiring, an aluminum-silicon alloy, a metal such as titanium, tungsten, or tantalum is used, and those formed by laminating these materials in a single layer or multiple layers are used. Moreover, ITO which is the same material as the anode 10 is formed on the outermost layer of the cathode wiring. Simultaneously with the formation of the anode 10, by forming ITO on the outermost layer of the cathode wiring, corrosion of the cathode wiring in the photolithography process in the manufacturing process can be prevented.

  The auxiliary cathode wiring is provided at the end of the cathode 11 for the purpose of assisting the energization between the cathode 11 and the cathode wiring. As a material for forming the auxiliary cathode wiring, a metal having high conductivity such as aluminum is used, and the auxiliary cathode wiring is formed by vacuum deposition or sputtering through a mask.

(Sealing layer)
On the element substrate 20A, a sealing layer F covering the light emitting element 21 and having a plurality of protective layers laminated on the entire surface is formed. As the sealing layer F, the organic EL device 1 of the present embodiment includes an electrode protective layer 17, an organic buffer layer 18, and a gas barrier layer 19.

  On the element substrate 20 </ b> A, an electrode protection layer 17 is formed on the entire surface of the element substrate 20 </ b> A, covering the end surfaces of the cathode wires and covering the surfaces of the cathode wires, the auxiliary cathode wires, and the cathode 11. This electrode protective layer 17 can suppress damage to the cathode 11 and the functional layer 12 therebelow as thin as 10 nm. Further, it also has a function as a gas barrier layer that prevents moisture from entering the light emitting element 21.

  The electrode protective layer 17 can be formed using a high-density plasma film forming method such as an ECR sputtering method or an ion plating method. Before the formation, it is preferable to improve the adhesion of the film formed by oxygen plasma treatment.

  The electrode protective layer 17 is preferably composed of a silicon compound such as silicon oxynitride or silicon nitride in consideration of transparency, adhesion, water resistance, insulation, and gas barrier properties. Among these, silicon oxynitride is preferable because it can be a colorless and transparent film having desired moisture permeability by changing the ratio of oxygen and nitrogen contained therein. In this embodiment, the electrode protective layer 17 is formed using silicon oxynitride.

  The film thickness of the electrode protective layer 17 is preferably 100 nm or more, and the upper limit of the film thickness is preferably set to 200 nm or less in order to prevent generation of cracks due to stress generated by covering the partition wall 13. In the present embodiment, the electrode protective layer 17 is formed as a single layer, but may be stacked as a plurality of layers. For example, the electrode protective layer 17 may be composed of a low elastic modulus lower layer and a high water resistance upper layer.

  On the electrode protective layer 17, an organic buffer layer 18 is formed inside the electrode protective layer 17. The organic buffer layer 18 is disposed so as to fill the uneven portions of the electrode protection layer 17 formed in an uneven shape due to the shape of the partition wall 13 and to relax the undulations. The organic buffer layer 18 has a function of relieving stress generated by warping or volume expansion of the element substrate 20A and preventing the electrode protective layer 17 from peeling from the partition wall 13. Further, since the undulations on the surface of the electrode protective layer 17 are relaxed on the upper surface of the organic buffer layer 18, there is no portion where stress is concentrated in the gas barrier layer 19 described later, and the generation of cracks can be prevented.

  The organic buffer layer 18 is preferably formed of an organic compound material that is excellent in fluidity and has no solvent or volatile component, and is a raw material for the polymer skeleton, and has an epoxy group as such a forming material. Epoxy monomers / oligomers having a molecular weight of 3000 or less can be suitably used. Here, a raw material having a molecular weight of less than 1000 is a monomer, and a raw material having a molecular weight of 1000 to 3000 is an oligomer. For example, bisphenol A type epoxy oligomer, bisphenol F type epoxy oligomer, phenol novolac type epoxy oligomer, polyethylene glycol diglycidyl ether, alkyl glycidyl ether, 3,4-epoxycyclohexenylmethyl-3 ′, 4′-epoxycyclohexene carboxylate, There are ε-caprolactone-modified 3,4-epoxycyclohexylmethyl 3 ′, 4′-epoxycyclohexanecarbochelate, and these may be used alone or in combination.

  Further, the forming material of the organic buffer layer 18 includes a curing agent that reacts with the epoxy monomer / oligomer. As such a curing agent, an agent that forms a cured film having excellent electrical insulation and adhesiveness, high hardness, toughness and excellent heat resistance is suitably used, and it has excellent transparency and little variation in curing. The polymerization type is preferred. For example, 3-methyl-1,2,3,6-tetrahydrophthalic anhydride, methyl-3,6-endomethylene-1,2,3,6-tetrahydrophthalic anhydride, 1,2,4,5-benzene Acid anhydride curing agents such as tetracarboxylic dianhydride and 3,3 ′, 4,4′-benzophenone tetracarboxylic dianhydride are preferred. The material for forming the organic buffer layer 18 to which these curing agents are added behaves as an excellent thermosetting resin.

  Furthermore, low-temperature curing is facilitated by adding trace amounts of amine compounds such as alcohols and aminophenols that have a high molecular weight and are difficult to volatilize such as 1,6-hexanediol as reaction accelerators that promote the reaction (ring opening) of acid anhydrides. Become. These curings are performed by heating in the range of 60 ° C. to 100 ° C., and the cured film becomes a polymer having an ester bond.

  In addition, a cation-releasing photopolymerization initiator often used to shorten the curing time may be used, but it is preferable that the reaction is slow so that the curing shrinkage does not rapidly progress, and the viscosity decreases due to heating after coating. It is preferable to finally form a cured product using thermosetting so as to promote flattening. Furthermore, a silane coupling agent that improves the adhesion to the cathode 11 and the gas barrier layer 19 and a water capturing agent such as an isocyanate compound may be mixed therein.

  The viscosity of each raw material is preferably 1000 mPa · s (room temperature: 25 ° C.) or more. This is because a non-light-emitting region called a dark spot is not generated by penetrating into the functional layer 12 immediately after coating. In addition, the viscosity of the buffer layer forming material obtained by mixing these raw materials is preferably 500 mPa · s to 20000 mPa · s, particularly 2000 mPa · s to 10,000 mPa · s (room temperature). Moreover, it is preferable that the water content is a material adjusted to 1000 ppm or less.

  The optimum film thickness of the organic buffer layer 18 is preferably 2 μm or more and 5 μm or less. If the organic buffer layer 18 is thicker, it is easier to prevent the gas barrier layer 19 from being damaged when foreign matter is mixed in. However, if the combined thickness of the organic buffer layer 18 exceeds 5 m, the color filter 25 and the functional layer 12 described later are used. This is because the light that escapes to the side surface increases as the distance increases, and the light extraction efficiency decreases.

  A gas barrier layer 19 is formed on the electrode protective layer 17 so as to cover the entire surface including the end portion of the organic buffer layer 18 and cover substantially the entire surface of the electrode protective layer 17. The gas barrier layer 19 has a function of preventing oxygen and moisture from entering the light-emitting element 21, thereby suppressing deterioration of the light-emitting element 21 due to oxygen and moisture. In consideration of transparency, gas barrier properties, and water resistance, the gas barrier layer 19 is preferably formed using a silicon compound containing nitrogen, that is, silicon nitride, silicon oxynitride, or the like. In this embodiment, the gas barrier layer 19 is formed using silicon oxynitride.

  The gas barrier layer 19 can be formed using a high-density plasma film forming method such as an ECR sputtering method or an ion plating method. Before the formation, it is preferable to improve the adhesion of a film formed by performing oxygen plasma treatment on the formation surface. The film thickness of the gas barrier layer 19 is preferably 100 nm or more in order to prevent the gas barrier layer 19 from being damaged and to ensure gas barrier properties. Moreover, in order to prevent a crack when covering the edge part of the organic buffer layer 18, and uneven | corrugated | grooved parts, such as cathode wiring, it is preferable that it is 800 nm or less. In the present embodiment, the gas barrier layer 19 is formed as a single layer, but may be stacked as a plurality of layers.

(Color filter layer)
In the color filter layer 25, colored layers for modulating transmitted light into any one of red (R), green (G), and blue (B) are arranged in a stripe pattern. The colored layer is formed by mixing a pigment or dye showing red, green, or blue with a resin layer such as an acrylic resin. Moreover, it is good also as providing colored layers, such as light blue, light cyan, and white, as needed. In this embodiment, the spin coat method is used so that the colored layers are adjacent to each other. However, a black matrix formed by transferring a colored layer formed on another sheet or a resin colored in black is used. A layer may be provided and a colored layer may be formed by an inkjet method. Further, an organic flattening layer 26 may be provided on the color filter layer 25 to eliminate a step caused by the colored layer.

(Lenticular lens)
The feature of the element substrate 20A is that white light emitting elements 21 for red, green, and blue are arranged in two rows, such as red, red, green, green, blue, and blue. Therefore, the odd-numbered column can display the right-eye image (first pixel), and the even-numbered column can display the left-eye image (second pixel) independently. Each of the colored layers is disposed corresponding to the two rows of the light emitting elements 21 that emit white light. Further, as shown in the perspective view of FIG. 1, lenticular lenses 27 are formed at positions corresponding to the respective colored layer rows. The lenticular lens 27 is formed in a cylindrical shape by heating after an acrylic resin is formed in a stripe shape by a spin coat method, but a transfer method using a mold such as a nanoimprint method may be used.

(Seal layer and protective substrate)
Finally, the element substrate 20A and the protective substrate 30 are bonded to each other through the seal layer 33, thereby protecting the light emitting element 21 formed on the element substrate 20A from an external force. In the present embodiment, since the element substrate 20A and the protective substrate 30 are bonded together in nitrogen under atmospheric pressure, the seal layer 33 suitably seals nitrogen in the gap between the substrates. Alternatively, other inert gas such as argon, normal air, or an optically transparent liquid material having a refractive index lower than that of the lenticular lens 27 may be filled. Further, the protective substrate 30 may be an optically transparent substrate. Examples of the transparent substrate include inorganic materials such as glass and silicon nitride, organic polymers (resins) such as acrylic resins and polycarbonate resins, and materials having optical transparency such as composite materials thereof.

  The forming material of the sealing layer 33 is made of a resin material that is cured by ultraviolet rays and has an improved viscosity. Preferably, an epoxy monomer / oligomer having an epoxy group and having a molecular weight of 3000 or less is used. Here, monomers having a molecular weight of less than 1000 are monomers, and those having a molecular weight of 1000 to 3000 are oligomers. Examples of such a forming material include bisphenol A type epoxy oligomer, bisphenol F type epoxy oligomer, phenol novolac type epoxy oligomer, 3,4-epoxycyclohexenylmethyl-3 ′, 4′-epoxycyclohexene carboxylate, ε- There are caprolactone-modified 3,4-epoxycyclohexylmethyl 3 ′, 4′-epoxycyclohexanecarbochelate, and these are used alone or in combination.

  Further, the forming material of the seal layer 33 includes a curing agent that reacts with the epoxy monomer / oligomer. Depending on the type of curing agent to be added, the epoxy resin can be either a thermosetting type or a photocurable type. Here, a photoreactive initiator that causes a cationic polymerization reaction mainly by ultraviolet irradiation, such as a diazonium salt, diphenyliodonium salt, trifellsulfonium salt, sulfonate ester, iron arene complex, silanol / aluminum complex, is suitable. Used. The material for forming the seal layer 33 to which these curing agents are added behaves as a light (ultraviolet) curable resin.

  The viscosity at the time of applying the forming material of the seal layer 33 is preferably 10 Pa · s or more and 200 Pa · s or less (room temperature). In addition, when an additive called a cation hold agent is used so that the viscosity gradually increases after ultraviolet irradiation, the light irradiation step after bonding can be eliminated, and the forming material of the seal layer 33 hardly flows. Therefore, the bonding process is facilitated. Further, even a narrow seal width of 1 mm or less is preferable because the seal layer 33 can be prevented from being ruptured and the filler after sticking can be prevented from sticking out. Moreover, it is preferable that the water content is a material adjusted to 1000 ppm or less.

  Usually, the material for forming the seal layer 33 is a spherical particle (spacer) having a predetermined particle diameter for controlling the distance between the substrates, or a scaly or massive inorganic material (inorganic filler) for adjusting the viscosity. Etc.) are often mixed. However, since these fillers may damage the gas barrier layer 19 at the time of bonding and pressure bonding, in this embodiment, a seal layer forming material in which these fillers are not mixed is used.

  With such a configuration of the present embodiment, the light emitted from the red light emitting element 41R for the right eye and the red light emitting element 41L for the left eye in FIG. 3 passes through each of the colored layers and is then left and right of the drawing by the lenticular lens 51. The light emitted from the red light emitting element 41R for the right eye is emitted to the right eye of the observer, and the light emitted from the red light emitting element 41R for the left eye is emitted to the left eye side of the observer. Similarly, the right-eye green light-emitting element 42R and the left-eye green light-emitting element 42L are also moved in the left-right direction by the lenticular lens 52, and the right-eye blue light-emitting element 43R and the left-eye blue light-emitting element 43L are also moved by the lenticular lens 53, respectively. Since it is sorted and emitted to the observer, the observer can observe a color parallax display.

(Second Embodiment)
4 to 5 are explanatory diagrams of an organic EL device according to the second embodiment of the present invention. The organic EL device 2 of the present embodiment is partially in common with the organic EL device 1 of the first embodiment. The only difference is the color arrangement of the white light emitting elements 21 of the element substrate 20A and the positional relationship between the corresponding color filter layer 25 and lenticular lens 27. Therefore, in this embodiment, the same code | symbol is attached | subjected about the component which is common in 1st Embodiment, and detailed description is abbreviate | omitted.

  In the cross-sectional view of FIG. 4, the white light emitting elements 21 of the element substrate 20 </ b> A are for different emission colors for each column such as red, green, blue, red, green, and blue. When the three light emitting elements 21 for red, green, and blue are defined as one color pixel, the odd-numbered color pixel (first color pixel) is the right-eye image and the even-numbered color pixel. The (second color pixel) displays the image for the left eye independently.

(Color filter layer)
In the color filter layer 25, red, green, and blue colored layers are arranged so as to correspond to the white light emitting elements 21 for red, green, and blue, respectively.

(Lenticular lens)
