Abstract:
An object of the present invention is to provide a simply configured liquid crystal display device capable of providing a high front luminance when light obliquely enters a micro lens array. The liquid crystal display device comprises: a pair of polarizing plates which sandwich a pair of substrates; a liquid crystal layer sandwiched by the pair of substrates; transmission openings formed in a pixel to limit the quantity of light which penetrates the liquid crystal layer; condensing elements formed on the side of one of the substrates, opposite to the side on which the liquid crystal layer is disposed, to condense light to the transmission openings; and a planar light-emitting element which emits light to be applied to the condensing elements; wherein the light to be emitted from the planar light-emitting element forms a certain angle with respect to its perpendicular when emitted; and wherein the position of the transmission opening is relatively shifted with respect to that of the condensing element so as to increase the quantity of light which penetrates the transmission opening, in association with the light-emitting direction of the planar light-emitting element.
