发明名称 Liquid crystal display device having a prism sheet between first and second light diffusion layers
摘要 In a liquid crystal display device capable of performing as both a transmissive display and a reflective display using a transmissive type liquid crystal display panel, the influence attributed to a shade as viewed from the oblique direction can be reduced so that favorable visibility can be ensured. In a liquid crystal display device including a transmissive type liquid crystal display panel which sandwiches a liquid crystal layer between a pair of substrates and a backlight which is arranged at a back face of the liquid crystal display panel and has a light source and a reflector, wherein the device is capable of performing as a transmissive display using light from the light source and as a reflective display using external light incident from a front face side of the liquid crystal display panel by reflecting the external light on the reflector, at least two or more light diffusion layers are arranged between the back-face-side substrate out of the pair of substrates and the reflector of the backlight.
