摘要： A liquid crystal display of a transflective IPS system in which a lateral electric field is applied to a liquid crystal layer. Polarization films are arranged on the entire surface of a transmissive display unit and a reflective display unit in a manner similar to a transmissive IPS system. An inner retardation layer whose retardation is equal to a half wave is formed in the reflective display unit. A retardation of the liquid crystal layer of the reflective display unit is set to a quarter wave. Thus, a reflective display can be performed in a wide range of environment from a light place to a dark place and a transmissive display of a wide viewing angle and high picture quality can be performed.

摘要： To improve the reflectivity or the transmissivity significantly, there is provided a liquid crystal display device including a liquid crystal display panel having a pair of substrates and liquid crystal sandwiched between the pair of substrates. The liquid crystal display panel includes a plurality of subpixels each having an active element, a pixel electrode, and a counter electrode, in which an electric field is generated by the pixel electrode and the counter electrode to drive the liquid crystal. The liquid crystal display device includes a light-shielding film and a color filter formed on a first substrate of the pair of substrates, a scanning line for supplying the active element with a scanning voltage, the scanning line being formed on a second substrate of the pair of substrates. The boundary region between the subpixels adjacent along the scanning line has no light-shielding film and no color filter.
