Abstract
A liquid crystal display device of the present invention is a transflective liquid crystal display device that is provided with a backlight, a liquid crystal cell (), and a reflective electrode () provided in the liquid crystal cell (), and that displays an image through both a reflective display region (a) and a transmissive display region (b). In this liquid crystal display device, a front-side λ/4 plate (wave plate) for a reflective display is further provided on a side from which external light enters the liquid crystal cell (), and a thin film () is provided, on the reflective electrode (), for correcting a change in chromaticity caused by wavelength dispersion due to the λ/4 plate.
