Abstract:
1. A liquid crystal display apparatus for a vehicle comprising: a liquid crystal display panel; a light source behind the liquid crystal display panel; and an optical filter interposed between the liquid crystal display panel and the light source for controlling a direction of a light passing through the liquid crystal display panel; wherein the optical filter has a plurality of horizontal louvers vertically arranged in a column and disposed perpendicularly to a surface of the liquid crystal display panel, wherein an upper surface of each of the horizontal louvers is configured to have a lower light reflectivity than a lower surface of each of the horizontal louvers, and configuration of each of the horizontal louvers allows a first light passing through the each louver from the upper surface to the lower surface, and prevents a second light passing through the each louver from the lower surface to the upper surface.
