    Abstract: A display device and a display method are provided. The display device includes: a light source; a light guide plate; and a liquid crystal display panel including a first substrate and a second substrate aligned with and assembled to the first substrate and a liquid crystal layer between the first substrate and the second substrate. A light transmitting pattern is provided in the light guide plate, and an incident light from the light source is configured to transmit through the light transmitting pattern of the light guide plate to form monochromatic lights of at least three colors. The light source is time-divisionally lit, so that the monochromatic lights of at least three colors are time-divisionally irradiated onto a same sub-pixel electrode on the first substrate in each frame time to form reflected lights, and then the reflected lights are modulated by the liquid crystal layer to be displayed.
