Abstract: The semiconductor device includes a plurality of pixels arranged in rows and columns, and first transistors fewer than the number of the plurality of pixels. The plurality of pixels each includes a photodiode and an amplifier circuit. The amplifier circuit holds the accumulated charge and includes at least a second transistor electrically connected to a cathode of the photodiode. The cathode of the photodiode in the pixel in an n-th row and the cathode of the photodiode in the pixel in an (n+1)-th row are electrically connected to the first transistor. The number n is a natural number. The pixel in the n-th row and the pixel in the (n+1)-th row are in an identical column.

Abstract: A display device includes a pixel which includes a first photosensor portion having a first photodiode for detecting visible light, which is provided together with a display element portion; and a pixel which includes a second photosensor portion having a second photodiode for detecting infrared rays, which is provided together with another display element portion. The second photosensor portion detects infrared rays included in external light, and selects an imaging element and adjusts sensitivity in accordance with the amount of infrared rays detected by the second photosensor portion.

Abstract: A touch sensor (touch panel) which can be formed over the same substrate as a display portion is provided. Alternatively, a touch sensor (touch panel) which does not cause degradation in the quality of an image displayed on a display portion is provided. The touch panel includes a light-emitting element and a microstructure in which a pair of electrodes facing each other is isolated with an insulating material. As the insulating material, an elastic material or a material having a hole is used so that a filler layer formed using the insulating material can be deformed when a movable portion operates. It is preferable to use a material which is softened or hardened by certain treatment (e.g., heat treatment or chemical treatment) after formation.
