DISPLAY DEVICE AND ELECTRONIC DEVICE PROVIDED WITH SAME

摘要

A display device provided with an environmental sensor formed in a peripheral region of an active matrix substrate. The characteristics of the environmental sensor are not easily deteriorated in time. The display device is provided with the active matrix substrate (2) having a pixel arranged region (8) wherein a plurality of pixels are arranged; a facing substrate (3) arranged to face the pixel arranged region (8) of the active matrix substrate (2); and a display medium (4) arranged in a space between the active matrix substrate (2) and the facing substrate (3). In the display device, a light sensor (11) is arranged in the peripheral region (9) existing around the pixel arranged region (8) on the active matrix substrate (2), and a surface protecting film (24) is formed of a same material as that of a part of a member constituting the active matrix substrate (2), for covering at least electrode sections (33, 34) of the light sensor (11) at an upper layer of the light sensor (11).
