Abstract
A displaying apparatus includes a display screen, and a light-shielding grating member having a plurality of light-shielding plates which are assembled in a matrix form in vertical and horizontal directions, the light-shielding grating member being disposed in front of the display screen. In the displaying apparatus, the respective light-shielding plates in the vertical and horizontal directions are inclined in directions to pass a predetermined visual point range when the respective light-shielding plates are virtually extended frontward, or the light-shielding grating member is inclined frontward and backward with respect to the display screen within a predetermined angle range. According to such a structure, external light obliquely injected into the display screen from the left, right, upper and lower sides can be shielded so as to improve a display contrast and visibility to prevent difficulties in seeing the image.
