Title:
Display device
Document Type and Number:
Japanese Patent JP5946878
Kind Code:
B2
Abstract:
When light generated in a light emitting layer of a display device is emitted through insulating films such as a planarizing film, an interlayer insulating film and a gate insulating film of a transistor, diffused reflection is caused due to slight-rough surfaces of the insulating films every time light passes through each insulating film. Accordingly, problems are caused in which stray light is caused, an outline of a pixel becomes indistinct, and a characteristic of the transistor is deteriorated. A display device according to the invention includes a transistor formed over a substrate, an insulating film with a light shielding property formed on the transistor, an opening for transmitting light therethrough formed in the insulating film with the light shielding property, and a light emitting element formed overlapping the opening.
