ABSTRACT:
A liquid crystal display apparatus includes a liquid crystal display panel, a backlight source behind the liquid crystal display panel, and an optical filter interposed between the liquid crystal display panel and the backlight source for controlling a direction of light passing through the liquid crystal display panel. The optical filter has a plurality of horizontal louvers vertically arranged in a column and perpendicularly disposed to a surface of the liquid crystal display panel. The differences in light reflectivity and transmittance between an upper surface and a lower surface of the louver give the optical filter a half mirror function that controls a direction of a passing light therethrough.
