PROJECTION TYPE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2020003739
Kind Code:
A
Abstract:
To hold a reflection type liquid crystal panel and a reflection type polarizing plate with high precision without increasing sizes of optical components of an optical system using a reflection type WG element.SOLUTION: The present invention relates to an image display device comprising: a color synthesis prism 16 which synthesizes a plurality of image lights from a plurality of image display elements; a plurality of polarizing separator elements 12R, 12G, and 12B which are arranged on optical paths of the plurality of image lights; a plurality of light transmission members 15R, 15G, and 15B which are fixed on a plurality of incidence surfaces where the plurality of image lights impinges on the color synthesis prism 16; and a holding member 20 which holds one pair of a corresponding light transmission member and a polarizing separator element among the plurality of light transmission members 15R, 15G, and 15B and the plurality of polarizing separator elements 12R, 12G, and 12B, the holding member 20 being stuck on side faces of the light transmission members 15R, 15G, and 15B.SELECTED DRAWING: Figure 4
