摘要： A backlight unit includes a light guide plate that includes a side surface that is an incidence surface that is normal to a first direction, a light source adjacent to the incidence surface, and a light conversion layer disposed on an upper surface of the light guide plate that changes a wavelength of light incident thereto. The light conversion layer includes a first portion and a second portion arranged in the first direction. The first portion is closer to the incidence surface in the first direction than the second portion, and the first portion is thinner than the second portion.

摘要： A display substrate includes a base substrate, a color filter layer and a retarder layer. The base substrate includes a first sub pixel area, a second sub pixel area and a third sub pixel area. The color filer layer is disposed on a front surface of the base substrate, and includes at least one of a magenta color filter, a cyan color filter and a yellow color filter in the first sub pixel area and the second sub pixel area and a white color filter in the third sub pixel area. The retarder layer is disposed on a rear surface of the base substrate opposite to the front surface of the base substrate. The retarder layer is configured to polarize light in the first sub pixel area and the second sub pixel area to form a first polarized light. The retarder layer is further configured to polarize the light in the third sub pixel area to form a second polarized light, the second polarized light being different from the first polarized light. Thus, a driving speed of a display apparatus may be decreased.

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.

摘要： 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.
