Image display apparatus with ambient light sensing system

An image display apparatus comprising:

• a display panel including a first insulating substrate where a pixel region is formed by arranging a plurality of pixels having a thin-film-transistor in a matrix form over the main face thereof and a second insulating substrate which is opposed and adhered to the main face of the first insulating substrate with a predetermined gap;
• a driver which is provided outside of the pixel region of the first insulating substrate and which drives pixels constituting the pixel region;
• and
• a printed circuit board where a display control circuit is mounted to supply a signal for display to the driver,
• wherein the image display apparatus has a plurality of light sensors including semiconductor films constituting an active layer which is the same layer as the thin-film-transistor of the pixel circuit, in the vicinity of the pixel region at the main face of the first insulating substrate, and
• wherein the plurality of light sensors have different wavelength bands of detected light.
