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 display apparatus is provided including a first substrate on which a plurality of organic light-emitting diodes are arranged. A second substrate is bonded to the first substrate. The second substrate includes a plurality of light control units respectively corresponding to the plurality of organic light-emitting diodes and a plurality of banks arranged between the plurality of light control units. The plurality of banks include a first bank having a deflection arrangement structure in which a fluorine-containing polymer is concentrated on a surface of a side of the first bank, and a second bank that does not have a deflection arrangement structure in which the fluorine-containing polymer is deflectively arranged.
