Abstract: A display panel includes a first display substrate including first to third pixel areas and a light blocking area that is adjacent to the first to third pixel areas and a second display substrate including first to third display elements respectively overlapping the first to third pixel areas. The first display substrate includes a base substrate, a first color filter overlapping the first pixel area and having a first color, a second color filter overlapping the second pixel area and having a second color different from the first color, a third color filter disposed on the base substrate, having a third color different from the first and second colors, and including a filter portion overlapping the third pixel area and a light blocking portion overlapping the light blocking area, and a light blocking member disposed on the light blocking portion and containing a black organic pigment.

Abstract: A liquid crystal display apparatus includes a backlight configured to emit red light, green light, and blue light for forming an image, a liquid crystal panel including a plurality of pixels through which light components supplied by the backlight respectively pass, configured to control transmittances of the plurality of pixels to form an image, and a backlight controller configured to control respective intensities of the red light, the green light, and the blue light emitted by the backlight. The backlight controller is configured to compensate for a black color coordinate value generated with respect to a predetermined color by controlling the backlight such that a second red light intensity and a second green light intensity are larger than a first red light intensity and a first green light intensity and a second blue light intensity are smaller than a first blue light intensity. A black color coordinate value may be made correspond to a white color coordinate value.

Abstract: A liquid crystal display device includes a first substrate, a second substrate facing the first substrate, and a liquid crystal layer between the first and second substrates. The liquid crystal layer includes a liquid crystal composition including an alkenyl liquid crystal and an antioxidant component including at least one selected from an antioxidant and a derivative thereof. In an embodiment, the antioxidant component is present in an amount of greater than 0 ppm and equal to or less than about 10,000 ppm relative to the total weight of the liquid crystal composition.
