An object of the present invention is to present a transmission type liquid crystal display device capable of achieving at least one of reduction of size of device and enhancement of performance of operation and display. A liquid crystal panel is divided into four divided regions in vertical direction in plan view, and corresponding to these divided regions, four ray emission light sources composed of fluorescent lamps are disposed vertically at the left side of a light guide plate, and the light emitted from the ray emission light sources illuminates the divided regions by way of the light guide plate. By turning on and off switches, the ray emission light sources are independently controlled to be lit up or put out, and only in a specific time including the time of all pixels of divided regions settling at target transmissivity, one ray emission light source out of ray emission light sources responsible for a corresponding divided region is lit up (illuminated, light-emitted).
