<p>A liquid crystal display device includes a frame (10), a linear light source (20), a liquid crystal cell (40), a light diffusing plate (50) and a positioning mechanism. The light diffusing plate is disposed between the frame and the liquid crystal cell and has 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 positioning mechanism positions 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.</p> |
