A transmissive liquid crystal display device is comprised not only of a light scattering plate disposed behind a liquid crystal display cell, a light diffusing film disposed behind this light scattering plate and a light source lamp and a reflective plate disposed behind this light diffusing film but also of a transparent plate disposed between the light diffusing film and the light source lamp. The reflective plate serves to direct backward propagating light from the source lamp towards the liquid crystal display cell, and the transparent plate has an indentation formed on its back surface. This indentation is shaped correspondingly to the shape of the light source lamp and contains the light source lamp inside.
