摘要： A liquid crystal display device has a pair of substrates disposed at an observer side and at the opposite side to the observer side, a plurality of pixel electrodes and an opposing electrode which are formed on the internal surfaces of the pair of substrates, a reflective layer, and liquid crystal sealed between these substrates. Each pixel electrode has a reflective display region corresponding to the reflective layer for reflecting light that enters from the observer side to the observer side, and a transmissive display region for allowing light that enters from the opposite side to pass therethrough to the observer side. A liquid crystal layer thickness adjusting layer is formed on the internal surface of the substrate at the observer side, for setting the liquid crystal layer thickness in the reflective display region to be smaller than the liquid crystal layer thickness in the transmissive display region.
