ABSTRACT:
A display device is composed of a light source device and a transmissive liquid crystal display panel, and the light source device is provided with a transparent/scattering switching element capable of switching between states in which incident light is transmitted or scattered. Pixels for displaying are disposed in the form of a matrix in the transmissive liquid crystal display panel, and the need for another power supply and signals for the transparent/scattering switching element is eliminated by driving the transparent/scattering switching element using the signals and power supply for driving the pixels. The drive power source of the transparent/scattering switching element for controlling scattering can be made smaller and less costly in a display device that is capable of switching the range of viewing angles.
