Abstract: A display panel includes a light source section, a light guide section, a liquid crystal layer, a partition section, a display section, and a diffusion section. The light source section can emit red light, green light, and blue light. A light source light emitted from the light source section enters the light guide section. The red light, the green light, and the blue light that have passed through the light guide section enter the liquid crystal layer. The partition section partitions the liquid crystal layer into plural pixel regions. An image formed by the red light, the green light, and the blue light emitted from the pixel regions is displayed on the display section. The diffusion section is provided in the light guide section and diffuses the red light, the green light, and the blue light that have entered the light guide section into the light guide section.

Abstract: FIG. 1 is a front view of a display screen with graphical user interface showing my new design; and,
FIG. 2 is an enlarged view of the area 2 indicated by the single dot-dash broken lines in FIG. 1.
The evenly-spaced broken lines depict portions of the display screen with graphical user interface that form no part of the claimed design. The areas indicated by the single dot-dash broken lines shown in FIG. 1 illustrate the boundary of enlarged area of the design. The “2” indicia and splined curve indicated by the single dot-dash broken lines in FIG. 1 identify the enlarged area. The single dot-dash broken lines form no part of the claimed design.

Abstract: A display device includes: a display panel with pixels; a light source with light emission points; an acquirer configured to acquire viewpoint information; and a controller configured to control image display based on the viewpoint information on positions of viewpoints and an arrangement direction of the viewpoints. The controller is configured to drive some or all of pixels positioned on straight lines each connecting a corresponding one of the light emission points to a corresponding one of the viewpoints based on a relative rotation angle between the display panel and the arrangement direction and a relative positional relation between the viewpoints and the light emission points. The light emission points are individually switchable between a turned-on state and a turned-off state. A pitch of the light emission points is smaller than a pitch of light emission points controlled to be turned on when outputting an individual image to each viewpoint.
