Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3220783
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize thinned large-screen display where a joint is made inconspicuous and a high-definition picture by composing displayed pictures of plural liquid crystal display element so that space is not left on a screen and marking the joint of the displayed pictures on the screen inconspicuous by a matrix-state light shielding layer.
SOLUTION: Light 80 made incident on a light incident surface of a collimating means 10 is totally reflected on a boundary surface between a high refractive index part and a low refractive index part, becomes a pseudo point light source on a light outgoing surface having high refractive index, and is turned into parallel beams 81 by a microlrns, so that the parallel beams 81 are efficiently obtained. Then, the picture displayed on the display screen of the liquid crystal display element 40 is formed to be an unmagnified state at a specified position on the element 40 in the normal direction of the element 40 by an image-formation means 30 but it is actually formed to be still the unmagnified state in an oblique direction by an optical path changing means 50. Thus, the pictures from the elements 40 are joined with not space in between and formed on the screen 70. Since the space between the display elements 40 is hidden by the effect of a black matrix 71 arranged on the screen 70, the picture without space is obtained.
