Abstract: A display panel includes a first base substrate, a second base substrate facing the first base substrate, an insulating structure including a non-pad portion having an end aligned with a side surface of the second base substrate and a pad portion having an end laterally recessed from the side surface of the second base substrate, a pixel overlapping a display area and disposed between the first and second base substrates, a signal line on the first base substrate and connected to the pixel, and a connection pad including a portion disposed in a connection region defined between the side surface of the second base substrate and the end of the pad portion. The signal line overlaps the pad portion. The connection pad is in contact with the signal line. The insulating structure is disposed between the first and second base substrates and overlaps a non-display area outside the display area.

Abstract: A display apparatus includes pixel areas and a light blocking area between the pixel areas. The display apparatus includes a first base substrate, a thin film transistor, and first, second, and third color filters. The first color filter has a first color, the second color filter has a second color different from the first color, and the third color filter has a third color different from the first and second colors. In the light blocking area, the thin film transistor, the first color filter, and the third color filter at least partially overlap each other. The second color filter in at least one pixel area is connected to an adjacent second color filter disposed in an adjacent pixel area by a bridge portion, and the bridge portion is formed of the same material as the second color filter and is disposed in the light blocking area.

Abstract: A liquid crystal display device includes first, second, third, and fourth pixel electrodes, each including a stem portion and a branch portion to define a plurality of domains, a common electrode opposing each of the first, second, third, and fourth pixel electrodes, and a liquid crystal layer between each of the common electrodes and a corresponding one of the first through fourth pixel electrodes, wherein an overall planar area of the stem portion and the branch portion of the fourth pixel electrode is smaller than an overall planar area of the stem portion and the branch portion of each of the first through third pixel electrodes.

Abstract: Deterioration of image quality in a display device due to kickback voltages may be reduced or prevented by varying parasite capacitance, the size of the semiconductor layer, and/or storage capacitance in each of thin film transistors for the pixels in the display. Various embodiments of display devices capable of reducing or preventing kickback voltages are disclosed.

Abstract: A display device includes: a base substrate including a pixel area at which an image is displayed; a light blocking pattern on the base substrate; a thin film transistor on the light blocking pattern; a gate line connected to the thin film transistor and lengthwise extending in a first direction; a data line connected to the thin film transistor and lengthwise extending in a second direction; and a pixel electrode in the pixel area and spaced apart from the gate line in the second direction. The light blocking pattern includes: a first light blocking pattern lengthwise extending in the first direction; and a second light blocking pattern overlapping the thin film transistor. The first light blocking pattern overlaps the gate line and the pixel electrode spaced apart from each other in the second direction.
