Abstract: A liquid crystal display (LCD) device capable of perventing impurities from permeating into a channel area of a switching element, the LCD device including: a gate electrode above a substrate; a semiconductor layer which overlaps the gate electrode; a drain electrode and a source electrode which overlap the semiconductor layer; an ohmic contact layer between the semiconductor layer and the drain electrode and between the semiconductor layer and the source electrode; a pixel electrode which is connected to one of the drain electrode and the source electrode; and a gate insulating layer between the gate electrode and the semiconductor layer, the gate insulating layer comprising fluorine. A concentration of the fluorine is decreasing, as the fluorine of the gate insulating layer being more adjacent to the substrate.

Abstract: A polarizer includes a substrate; a plurality of metal lines on the substrate, the plurality of metal lines each having a first width and a first height and being spaced apart from and parallel to each other with a first gap therebetween; and a hydrophobic coating layer on the metal line. The polarizer may be directly formed on the substrate, allowing for manufacture of light-weight and thin film structure of display device.

Abstract: A display apparatus includes a first pixel, a second pixel, a light sensor, and a light shield. The first pixel has a first light-emitting device which includes a first emission layer that emits light in a first wavelength band in a first direction. The second pixel has a second light-emitting device which includes a second emission layer to emit light in a second wavelength band in a second direction different from the first direction. The second emission layer is below the first emission layer of the first light-emitting device. The light sensor senses light in the second wavelength band emitted from the second pixel and reflected by an object. The light shield is arranged along a light path incident to the light sensor.
