Abstract:
1. A liquid crystal display device comprising: a frame; a linear light source attached to the frame at a specific position; a liquid crystal cell attached to the frame; a light diffusing plate disposed between the frame and the liquid crystal cell, and having an optical processing region formed in a first direction from a first side portion of the light diffusing plate to a second side portion of the light diffusing plate, the optical processing region being printed on only one side of the light diffusing plate; and a positioning mechanism positioning the light diffusing plate with respect to the frame with a middle portion of at least one of the first and second side portions of the light diffusing plate in a second direction perpendicular to the first direction being used as a reference to align the optical processing region of the light diffusing plate with the linear light source in the second direction.
