Definitions
- the present invention relates to a mirror device having a light emitting function including an organic electroluminescence element.
- An organic electroluminescent element is configured by, for example, sequentially laminating an organic layer including an anode, a light emitting layer, and a cathode on a transparent glass substrate. By injecting current into the organic layer through the anode and the cathode, the electroluminescence ( Hereinafter, the light-emitting element expresses EL).
- An organic EL element is a self-luminous surface-emitting device, and is used for a display device or a lighting device.
- an EL illumination built-in mirror in which an organic EL element is arranged in a frame shape around a mirror and an object such as a user's face can be projected on the mirror (see Patent Document 1).
- JP 2003-217868 A Japanese Patent No. 2625177
- the sun visor assembly described in Patent Document 2 also has a problem in that uniform light emission is difficult because the illumination portions by the lamps are directly provided in front of both sides of the mirror surface.
- the above mirror device has a drawback that the thickness of the entire mirror device is increased because the light emitting part is simply added before and after the mirror.
- an example of a problem is to provide a mirror device that has a light reflecting function and can suppress the increase in the thickness of the device and emit light to the front surface.
- the mirror device of the present invention is a mirror device having a translucent substrate and at least one organic EL element carried on the back surface of the translucent substrate, and emitting light from the front surface of the translucent substrate.
- the organic EL element has an organic layer including a light emitting layer stacked between a translucent electrode and a reflective electrode facing each other.
- the translucent electrode is formed on the translucent substrate; Each having an area smaller than the area of the translucent electrode and having a plurality of metal mirror surface portions distributed on the front surface of the translucent substrate so as to face the light emitting layer. To do.
- FIG. 1A and 1B are a front view and a partially enlarged front view in which a part of a mirror device of an organic EL panel according to Embodiment 1 of the present invention is cut away.
- FIG. 2 is a sectional view taken along the line CC in FIG.
- FIG. 3 is an enlarged cross-sectional view of a part of the mirror device of the organic EL panel according to the first embodiment.
- FIG. 4 is a schematic sectional view of a part of the organic EL panel showing the operation of the mirror device of the organic EL panel shown in FIG.
- FIG. 5 is a schematic sectional view of a part of a mirror device of an organic EL panel according to a modification of the first embodiment.
- FIG. 6 is a front view and a partially enlarged front view in which a part of a mirror device of an organic EL panel according to another modification of the first embodiment is cut away.
- FIG. 7 is a partial enlarged front view of a part of a mirror device of an organic EL panel according to another modification of the first embodiment.
- FIG. 8 is a partial enlarged front view of a part of a mirror device of an organic EL panel according to another modification of the first embodiment.
- FIG. 9 is a partial enlarged front view of a part of a mirror device of an organic EL panel according to another modification of the first embodiment.
- FIG. 10 is a partial enlarged front view of a part of a mirror device of an organic EL panel according to another modification of the first embodiment.
- FIG. 11 is a schematic sectional view of a part of the mirror device of the organic EL panel according to the second embodiment of the present invention.
- FIG. 12 is a schematic sectional view of a part of the mirror device of the organic EL panel according to the third embodiment of the present invention.
- FIG. 13 is a schematic sectional view of a part of the mirror device of the organic EL panel according to the fourth embodiment of the present invention.
- FIG. 14 is a schematic sectional view of a part of the mirror device of the organic EL panel according to the fifth embodiment of the present invention.
- FIG. 15 is a schematic sectional view of a part of a mirror device of an organic EL panel according to Embodiment 6 of the present invention.
- FIG. 16 is a schematic sectional view and a partial sectional view of a part of a mirror device for an organic EL panel according to a seventh embodiment of the present invention.
- FIG. 1 shows a configuration of a mirror device that is an organic EL panel OELD of Embodiment 1 of the present invention.
- the organic EL panel OELD includes a plurality of organic EL elements OEL partitioned by banks BK on a light-transmitting flat substrate 1 such as glass or resin.
- the bank BK is made of a dielectric material such as optical glass or optical resin.
- the organic EL element OEL has strip-shaped light emitting portions each extending in the y direction of the xy main surface of the substrate 1.
- the organic EL element OEL is a group of organic EL elements R, G, and B that emit light of different emission colors of red light emission R, green light emission G, and blue light emission B from the front surface 1 a of the translucent substrate 1.
- the organic EL elements R, G, and B are juxtaposed in parallel on the substrate 1.
- the organic EL elements OEL of RGB emission colors that emit red, green, and blue emission colors are arranged as a set in the x direction.
- the organic EL panel OELD includes the above-described banks and organic EL elements, and a plurality of metal mirror surface portions MIR distributed on the front surface 1a of the substrate 1.
- the plurality of metal mirror surface portions MIR are formed in stripes by alternately arranging metal mirror surface portions MIR, which are strip-shaped light reflecting portions extending in the y direction, and gaps SP in the x direction.
- the metal mirror surface portions are indicated by hatching in an enlarged portion of the metal mirror surface portions MIR juxtaposed in a matrix form indicated by white arrows.
- each of the metal mirror surface portions MIR has a width that covers the bank BK when viewed from above, and the metal mirror surface portions MIR of the same width are evenly arranged on the light emitting portion.
- Each of the plurality of metal mirror surface portions MIR has an area smaller than the area of each light emitting portion of the organic EL element OEL.

発光層3cは赤、緑及び青発光の独立した発光層であってもそれらの混合発光層であってもよい、また、正孔輸送の性質を有する化合物(正孔輸送性化合物)、或いは、電子輸送の性質を有する化合物(電子輸送性化合物)を含有させることもできる。有機EL材料をドーパント材料として使用し、正孔輸送性化合物や電子輸送性化合物などをホスト材料として適宜使用してもよい。有機EL材料については特に限定はなく、所望の発光波長で発光し、発光効率が良好である物質を用いればよい。
電子輸送層3dは、有機EL素子の発光効率を更に向上させることを目的として設けられるもので、電界を与えられた電極間において陰極から注入された電子を効率よく発光層の方向に輸送することができる電子輸送性化合物より形成される。
電子注入層3eは、陰極から注入された電子を効率良く電子輸送層や発光層へ注入する役割を果たす。例えば、電子注入層3eには、バソフェナントロリンなどの含窒素複素環化合物や8-ヒドロキシキノリンのアルミニウム錯体などの金属錯体に代表される有機電子輸送化合物が挙げられる。また、有機電子輸送化合物の電子注入層3eに電子供与性材料をドープすることにより、電子注入効率を高めることができる。電子供与性材料には、例としては、ナトリウムやセシウムなどのアルカリ金属、バリウムやカルシウムなどのアルカリ土類金属、それらの化合物(CsF、Cs2CO3、Li2O、LiF)や、ナトリウム、カリウム、セシウム、リチウム、ルビジウムなどのアルカリ金属などが用いられる。
陰極の反射電極4の材料としては、効率良く電子注入を行う為に仕事関数の低い金属が含まれることが好ましく、例えば、スズ、マグネシウム、インジウム、カルシウム、アルミニウム、銀などの適当な金属又はそれらの合金が用いられる。具体例としては、マグネシウム-銀合金、マグネシウム-インジウム合金、アルミニウム-リチウム合金などの低仕事関数合金電極が挙げられる。反射電極4はスパッタ法や真空蒸着法などにより有機層3上に、単層膜、又は多層膜として形成され得る。なお、反射電極4の反射作用を維持する厚さであれば膜厚は限定されない。
