ABSTRACT:
An LCD device includes a plurality of pixels each having a slope area configured by a plurality of layers. A shielded element shielded by a black matrix has an inner edge located at a distance X apart from the outer edge of the slope area, the distance X being expressed by the formula: x=(T1/cos β)×sin(α−β), wherein α and β are incidence angle and refracted angle, respectively, of the incident light at an interface between the layers having different refractive indexes in the slope area, and T1is a thickness of the underlying layer forming the interface.
