Abstract: A display device includes a display panel including pixels arranged in a matrix form along first and second directions crossing each other, a backlight unit configured to generate and provide a first light to the display panel, and a color conversion layer. Each pixel includes first and sub-pixels spaced apart from each other. The color conversion layer includes a first sub-color conversion layer overlapping the first sub-pixel and configured to receive the first light and to emit the second light having a wavelength different from that of the first light, and a second sub-color conversion layer overlapping the second sub-pixel, spaced apart from the first sub-color conversion layer and configured to receive the first light and to emit the first light. In a plan view, areas of the first and second sub-color conversion layers are different from each other.

Abstract: A liquid crystal display apparatus includes a gamma mapping unit configured to receive red, green, and blue image information from an external device. During the first field, the gamma mapping unit generates first to third data signals for controlling the first to third pixels based on the red, green, and blue image information in synchronization with the backlight unit. During the second field, the gamma mapping unit generates fourth and fifth data signals for controlling the first and second pixels based on at least one of the first to third data signals or based on the red, green, and blue image information. As the quantity of the second color light leaked is adjusted through the first and second color filters in the second field, a color reproduction range and brightness of the liquid crystal display panel are improved. Thus, the display quality of the liquid crystal display apparatus is improved.
