Abstract:
1. A display apparatus comprising: a display portion which displays a first image and a second image different from the first image to create a stereoscopic image by means of display elements; a separator situated away from the display portion and configured to separate the first and second images from each other; and an adjuster configured to adjust a shape of the separator, wherein the display portion includes a display surface in which the display elements are aligned in a vertical direction, each of the display elements includes different regions in luminance along a vertical line, the separator includes a barrier portion configured to block image light emitted from the display portion, the barrier portion includes a contour portion which defines a shape of at least one opening that allows transmission of the image light, the contour portion includes a first contour and a second contour facing the first contour, the first and second contours define a continuous opening region which is inclined at a predetermined angle from the vertical line, at least one contour of the first and second contours forms protrusions which periodically protrude toward the opening region, the opening region is inclined at an inclination angle θ from the vertical line, and the adjuster makes widths of the protrusions heterogeneous so that the widths of the protrusions get smaller than a value obtained by dividing an arrangement interval of the display elements in the vertical direction by a value of a number of the regions in the display element multiplied by cos θ, and sets a period of the protrusions within a predetermined range which includes an intermediate value between a first value obtained by dividing the arrangement interval by a first natural number and a second value obtained by dividing the arrangement interval by a second natural number obtained by incrementing the first natural number by 1.
