DISPLAY DEVICE AND ELECTRONIC DEVICE

摘要

A display device includes an optical sensor formed in a peripheral region of the display device. The optical sensor reacts to the near ultraviolet ray so as to prevent erroneous operation and effectively react for visible light. For this, the display device includes an active matrix substrate (2) having a pixel arrangement region (8) where a plurality of pixels are arranged on a base substrate (14). The display device is configured by including a photo-sensor (11) arranged in a peripheral region (9) existing around the pixel arrangement region (8), a display color filter (22) arranged to oppose to the base substrate (14) with respect to the arrangement position of a TFT (6), and an optical sensor color filter (23) arranged to oppose to the base substrate (14) with respect to the arrangement position of the photo-sensor (11).
