Display apparatus

A display apparatus comprising:

• an image display panel;
• a light source device that includes
• a light source that emits light, and
• a light guide member that is arranged on a back surface side of the image display panel as seen from a display surface of the image display panel, receives the light via a side surface of the light guide member with respect to a surface of the light guide member, the surface facing the image display panel, and has a plurality of divided areas arranged in a direction in which the light travels, each of the areas including a light modulation layer brought in a transmission state in which the light is transmitted through the light modulation layer or in a scattering state in which the light is scattered in the light modulation layer;
• and
• a control device that brings the light modulation layers of the areas in the scattering state in respective scattering control periods temporally different from each other, causes, as needed, the scattering state of the light modulation layer of one of the areas to temporally overlap a part of the scattering control period of another of the areas located farther from the side surface than said one area is, and controls, when bringing any one of the light modulation layers in the scattering state, the light source device with a drive pattern based on a distance between the side surface and the area including said one light modulation layer.

A display apparatus comprising:

• an image display panel that sequentially performs display scanning in a first direction;
• a light source device that includes
• a light source that emits light, and
• a light guide member that is arranged on a back surface side of the image display panel as seen from a display surface of the image display panel, receives the light via a side surface of the light guide member with respect to a surface of the light guide member, the surface facing the image display panel, and has a plurality of divided areas arranged in the first direction, each of the areas including a light modulation layer that guides the light in a second direction opposite to the first direction and that is brought in a transmission state in which the light is transmitted through the light modulation layer or in a scattering state in which the light is scattered in the light modulation layer;
• and
• a control device that brings, based on intensity of the light emitted from the areas to the image display panel in respective scattering control periods that are temporally different from each other and that are given to the respective areas in the first direction, the light modulation layer of one of the areas in the scattering state for the duration of the period based on a distance between the side surface and said one area.
