Abstract
An image input-output device includes a pixel which displays an image and reads an image. The pixel includes a photodetector element, a color layer, and a display element. The color layer is provided over the photodetector element and the display element is provided over the color layer, so that the distance between the photodetector element and the color layer is reduced. Accordingly, light is likely to enter the predetermined photodetector element through the predetermined color layer, and thus, even a color object can be read correctly.
