Abstract
According to the present invention, a material having a light-shielding property is used for a bank layer surrounding the edge of a light-emitting element. Accordingly, light which is not reflected by an object to be read out can be prevented from entering an image pick-up element, and information on the object to be read out can be correctly read out. The display device mounted with a read function according to the present invention includes a thin film transistor and an image pick-up element over a substrate having an insulating surface, an insulating layer covering a thin film transistor and an image pick-up element, a light-emitting element provided over the insulating layer, and a bank layer having a light-shielding property surrounding the edge of the light-emitting element. The bank layer has an opening portion in a position overlapping with the image pick-up element.
