としたことを特徴とする投影型表示装置。 In a projection type display device that projects a full-color image displayed by a display body onto a screen surface, the display body has three pixels: a red pixel, a green pixel, and a blue pixel.
In addition to displaying a full-color image with a pixel arrangement pattern in which pairs of pixels are arranged in an isosceles triangular shape, a prism plate formed by consecutively forming a plurality of prism portions is provided in the projection optical path from the display body to the screen surface. and each prism part of this prism plate divides the image light from the display body into three directions of light directed toward each apex of an isosceles triangle having a similar shape to the arrangement pattern of the one set of pixels. In addition to forming a triangular pyramidal prism portion with two inclined surfaces,
The angle of inclination of each inclined surface of each prism section is determined by the amount of deviation on the screen surface of light from two of the three directions of light divided by this prism section for one pixel of the image formed on the screen surface. The angle is approximately equal to the width, and the amount of deviation between the light in these two directions and the light in one other direction on the screen surface is approximately equal to the vertical width of one pixel of the image formed on the screen surface. A projection display device.
