Light-emitting device and light-emitting device manufacturing method

摘要

An organic EL display in which the film thickness of an organic emissive layer (63) is made uniform so as to increase the effective light emission area. An anode (61) and a common cathode (66) are formed for each pixel on the organic EL display. Switching by thin-film transistors causes current to flow between the anode and the cathode so that the organic EL element emits light. The organic EL element comprises a hole transport layer (62), the organic emissive layer (63), and an electron transport layer (64). Among a plurality of pixels disposed in a matrix configuration, the organic emissive layer is formed in common with adjacent pixels of the same color. Forming the organic emissive layer in common can prevent a decrease in the film thickness of the organic emissive layer at the edges of the shadow mask during vapor deposition and result in a uniform film thickness of the organic emissive layer. <IMAGE>
