Abstract: An optical sheet includes a light-passing base sheet, a plurality of light-passing first patterns formed on a front major surface of the base sheet, and a plurality of light-passing second patterns formed on a rear major surface of the base sheet. The first patterns protrude from the front surface of the base sheet, a top portion of each of the second patterns makes contact with the rear surface of the second patterns while a larger lower surface of each of the second patterns is exposed to serve as a light receiving surface. Voids having relatively low refractive indices are formed between the light-passing second patterns. The optical sheet employs just one base sheet in one embodiment, thereby reducing a manufacturing cost of the optical sheet.
Abstract translation: 光学片包括通光基片，形成在基片的前主表面上的多个通光第一图案和形成在基片的后主表面上的多个通光第二图案。 第一图案从基片的前表面突出，每个第二图案的顶部与第二图案的后表面接触，而每个第二图案的较大的下表面暴露以用作光 接收面。 在光通过的第二图案之间形成具有相对较低折射率的空隙。 光学片在一个实施例中仅使用一个基片，从而降低了光学片的制造成本。

Abstract: A display device includes a pressure sensing element. The pressure sensing element senses a pressure input applied thereto from the outside, and the display device is controlled based on the sensed pressure input. The pressure sensing element includes a contact sensing area to sense the pressure input and a defect sensing area to sense a defect. The pressure sensing element measures a resistance value in the defect sensing area and identifies whether at least one of lines of the pressure sensing element is disconnected.
