Abstract
A liquid crystal display device of high image quality is provided at a low cost, in which the viewing angle is restricted only in a specific direction. A liquid crystal display device of the present invention, which has a plurality of pixels in a matrix arrangement, includes: a first substrate; a second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; and a plurality of microlenses provided on a surface of the first substrate which is opposite to the liquid crystal layer, the microlenses being arranged so as to correspond to the plurality of pixels, and each of the microlenses having a curved surface configured to collect incoming light, wherein d satisfies the following relationship: d>p.((2n)2−1)½ where d is a thickness of the first substrate, p is an arrangement pitch of the plurality of pixels, and n is a refractive index of the major material of the first substrate.
