Abstract
A liquid crystal display device using a light source having a bright line in a visible region as a light source. On the inner surface of a transparent substrate such as a glass substrate constituting a liquid crystal display device, a laminate structure constituted by a transparent electrode, an alignment layer, and one or more transparent intermediate layers having a refractive index smaller than that of the transparent electrode layer and larger than that of the liquid crystal layer or the transparent substrate is formed. The thicknesses or the like of the layers are determined such that, at the bright line wavelengths of the light source, the sum of reflectances generated on the layer interfaces of the laminate structure is set to be not more than 0.5%.
