Abstract:
A substrate (100) is a light-transmitting substrate. A light-transmitting first electrode (110) is formed over the substrate (100). An insulating layer (150) is formed over the substrate (100) and the first electrode (110) and includes an opening (152) overlapping the first electrode (110). An organic layer (120) is located within at least the opening (152). A light-transmitting second electrode (130) is formed over the organic layer (120). An intermediate layer (200) is formed in at least a portion of a region of a lateral side of the first electrode (110) overlapping the first electrode (110). A refractive index of the intermediate layer (200) is between a refractive index of the substrate (100) and a refractive index of the first electrode (110).
