Abstract: A display device includes a light source, a liquid crystal panel including a first sub-pixel and a second sub-pixel adjacent to the first sub-pixel in a first direction, and an optical control element including a light shielding layer. Each of the first sub-pixel and the second sub-pixel has a first width in the first direction. The light shielding layer includes an opening portion having a second width in the first direction. The second width is 1.5 times the first width. In all of light rays irradiated from the light source and transmitting through the opening portion, an angle between a first light ray transmitting through the first sub-pixel and emitted to an outside and the second light ray transmitting through the second sub-pixel and emitted to the outside is less than or equal to 2 degrees.

Abstract: A display device includes: an image display panel including pixels each including a first to a forth sub-pixel that display a first color to a fourth color; and a signal processing unit. The signal processing unit stores an expanded color space, determines maximum set brightness as an upper limit value of brightness displayable within a range of the brightness in the expanded color space so that the maximum set brightness increases as a panel average input value decreases, determines an input expansion coefficient for expanding the color displayed by the image display panel to a color of the maximum set brightness, obtains the output signal of the first to forth sub-pixel based on the input signal of the first to third sub-pixel and the input expansion coefficient. The expanded color space is a color space that can extend a color of brightness higher than that in a standard color space.
