Patent attributes
A display apparatus includes a display unit having a display area in which a two-dimensional image is displayed, and an optical element configured by disposing a plurality of structural bodies for separating the image displayed in the display area into images observed at predetermined observation positions arranged at intervals in a horizontal direction. In the display area, pixels are arranged in a matrix pattern in the horizontal direction and in a vertical direction, and pixels having different planar shapes are arranged for each row in a certain cycle, and the structural bodies of the optical element are disposed to be tilted at an inclination which satisfies (J+0.5)/3 (J is an integer of 3 or more) with respect to the vertical direction with a number of pixels as a unit.
