Abstract:
Provided is a display apparatus which can easily bond a drive panel (10) and a sealing panel (20) together. The drive panel (10) includes organic electroluminescence devices (10R), (10G) and (10B) on a substrate for drive (11) and extracts light from the side of the organic electroluminescence devices (10R), (10G) and (10B). The sealing panel (20) includes a color filter (22) on a substrate for sealing (21). The drive panel (10) and the sealing panel (20) are disposed to face each other, and the whole facing surfaces of the drive panel (10) and the sealing panel (20) are bonded together with an adhesive layer (30). The adhesive layer (30) is cured with at least heat, and is made of only one coating liquid or a combination of two or more coating liquids for curing. A temporary fixing portion (30A) is formed in an edge portion of the adhesive layer (30). The temporary fixing portion (30A) is made of, for example, an ultraviolet cure resin, and is formed so as to straddle between the sealing panel (20) and the drive panel to align their relative positions.

An organic electroluminescence device having a luminous efficiency improved by increasing the reflectance of the anode and its producing method are disclosed. On a substrate (11), an anode (12), an organic layer (15) including a hole-injection thin-film layer (13), an insulating layer (14), and an emitting layer (15c), and a cathode (16) including a semitransparent electrode (16A) are provided in multilayer. The anode (12) is made of silver, a metal of high reflectance, or an alloy containing silver, and the hole-injection thin-film layer (13) contains chromium oxide. The light emitted from the emitting layer (15c) is multiply reflected between the anode (12) and the semitransparent electrode (16A) and outputted from the cathode (16). Since the reflectance of the anode (12) is high, the light emitted from the emitting layer (15C) can be outputted at high efficiency. The alloy of the anode (12) is preferably an alloy containing silver, palladium, and copper, and the content of silver is preferably 50 mass% or more.
