Abstract: A liquid crystal display device includes a liquid crystal display panel, a backlight unit under the liquid crystal display panel, and a guide panel surrounding the backlight unit. The guide panel includes a metal chassis, a first mold, and a second mold. The metal chassis has a plate shape, includes a plurality of through holes, and is formed of a metal material. The first mold is on at least a part of an upper surface and a lateral surface of the metal chassis and within the through holes and is formed of a light absorbing resin. The second mold is between the first mold and the backlight unit and is formed of a light reflecting resin.

Abstract: An organic light-emitting display (OLED) device with an integrated pressure sensor is provided. The OLED device includes a substrate, an organic light-emitting element, and a back-plate. The substrate has a thin-film transistor and has flexibility. The organic light-emitting element is connected to the thin-film transistor on the substrate. The back-plate supports the substrate under the substrate and has a pressure sensor configured to measure the intensity of a touch input. The OLED device with an integrated pressure sensor includes a pressure sensor configured to support a substrate and measure the intensity of a touch input, so that a separate pressure sensor attached to the display device in an add-on type touch screen panel can be eliminated.

Abstract: Provided is a backlight unit in which a light blocking film is attached between a reflective sheet and a circuit board of a light source unit to shield a space between the reflective sheet and the circuit board, thus suppressing the reflective sheet from being stripped and minimizing light leakage. The backlight unit includes the light source unit, a light guide plate, the reflective sheet, and the light blocking film.
