    Abstract: A method of manufacturing a wire grid polarizer for a display apparatus includes the steps of forming a first layer on a base substrate including an active area and a peripheral area surrounding the active area, forming a hard mask layer on the first layer, coating an imprint resin on the hard mask layer, forming an imprint resin pattern by imprinting a stamp on the imprint resin, wherein the stamp is larger than the base substrate, forming a hard mask pattern by patterning the hard mask layer using the imprint resin pattern, forming a wire grid pattern layer by pattering the first layer using the hard mask pattern, forming a photoresist pattern in the active area on the base substrate, removing the hard mask pattern and the wire grid pattern layer in the peripheral area using the photoresist pattern, and forming a capping layer on the wire grid pattern.

    Abstract: The display device includes a plurality of gate lines extending in a first direction, a plurality of data lines extending in a second direction intersecting the first direction, and a plurality of pixels connected to the gate lines and the data lines. A plurality of dots is defined by the pixels, each of the dots includes first to fourth pixels in a same pixel column arranged in the second direction, and the first to fourth pixels display first to fourth colors, respectively. The first to fourth pixels are connected to two or three gate lines among the gate lines. Three pixels among the first to fourth pixels have a same polarity, and the remaining one pixel among the first to fourth pixels has a different polarity than the three pixels.

    Abstract: A display device includes a first pixel group having first, second, third, and fourth pixels arranged along a column direction, and a second pixel group having fifth, sixth, seventh, and eighth pixels arranged along the column direction. A gate line is connected to the first, second, third, fourth, fifth, sixth, seventh, and eighth pixels. A first data line is connected to the first pixel, the third pixel, the fourth pixel, and the sixth pixel, and a second data line is connected to the second pixel, the fifth pixel, the seventh pixel, and the eighth pixel. The first pixel group and the second pixel group are alternately disposed along a row direction. This arrangement allows inversion driving wherein the first data line receives a voltage having a different polarity from that of the second data line so as to reduce line flickering and reduce power consumption in the display device.

    Abstract: A thin film transistor substrate includes a substrate and thin film transistors arranged in first and second directions above the substrate. Each thin film transistor includes a gate electrode, a drain electrode, a source electrode and a semiconductor layer. The drain electrode is above the gate electrode and includes a first drain oblique portion and a second drain oblique portion extending from an end portion of the first drain oblique portion. The source electrode is spaced apart from the drain electrode above the gate electrode and includes a first source oblique portion and a second source oblique portion extending from an end portion of the first source oblique portion. The semiconductor layer at least partially overlaps the gate electrode and includes a drain region to which the drain electrode is connected, a source region to which the source electrode is connected, and a channel region therebetween.
