Abstract
A display apparatus is provided which can detect light of a predetermined wavelength with a high degree of accuracy from within light incident from a screen by a simple configuration. The display apparatus includes a CF substrate (9) having a plurality of color filters (31) of different colors for passing light for displaying an image on the screen (55a) and an IR filter (33) provided in a region different from an arrangement region of the color filters of the different colors for passing light incident from the screen (55a), and a main sensor (19) provided on the rear side of the IR filter (33) for detecting light incident from the screen (55a) and passing through the IR filter (33). The IR filter (33) has a laminate of filter materials same as filter materials from which at least two or more ones of the color filters of the different colors are formed respectively.
