Patent ID: 7889292

Claim:
A liquid crystal display device comprising: a liquid crystal display panel having a first substrate, a second substrate located opposite the first substrate with a gap between the first substrate and the second substrate, and a liquid crystal layer held between the first substrate and the second substrate; a first polarizing plate located opposite the liquid crystal layer; a first polarizing reflection layer positioned opposite the first polarizing plate across the liquid crystal layer and located opposite the liquid crystal layer to reflect linearly polarized light polarized in one direction parallel to a plane of the liquid crystal display panel; a second polarizing plate positioned opposite the liquid crystal layer across the first polarizing reflection layer and located opposite the first polarizing reflection layer, the second polarizing plate having an absorption axis parallel to a polarizing direction of the linearly polarized light reflected by the first polarizing reflection layer; and a second polarizing reflection layer positioned opposite the liquid crystal layer across the first polarizing plate and located opposite the first polarizing plate, the second polarizing reflection layer reflecting linearly polarized light parallel to a direction of an absorption axis of the first polarizing plate.
