Abstract:
A display apparatus includes an image display panel, a light source device, and a control device. The light source device includes a light source that emits light and a light guide member arranged on the back surface side of the panel as seen from the display surface, receives the light via its side surface with respect to its surface facing the panel, and has divided areas arranged in a direction in which the light travels. Each area includes a light modulation layer brought in a light transmission state or in a light scattering state. The control device brings the layers in the scattering state in respective scattering control periods temporally different from each other. When bringing a light modulation layer in the scattering state, the control device controls the light source device with a drive pattern based on a distance between the side surface and the corresponding area.
