Abstract: A display device includes: an array of pixels disposed on a display area; a connection pad disposed on a pad area; a transmission line electrically coupled with the connection pad; and a conductive dummy pattern disposed under the transmission line. A part of the conductive dummy pattern overlaps the transmission line in a plan view. The transmission line transmits a driving signal or a power signal to the array of pixels. The connection pad includes a pad conductive layer electrically coupled with the transmission line, and a passivation layer disposed on the pad conductive layer. The passivation layer covers at least a side surface of the pad conductive layer and defines an opening overlapping the conductive dummy pattern and the transmission line in the plan view.

Abstract: A display device according to an embodiment includes: a substrate; and a plurality of pixels, the plurality of pixels including a first pixel, a second pixel and a third pixel. Each of the plurality of pixels including a gate line extends in a first direction; a first transistor and a second transistor connected with the gate line; a pixel electrode that includes a first subpixel electrode and a second subpixel electrode; a first bridge that connects the first subpixel electrode and the first transistor; and a second bridge that connects the second subpixel electrode and the second transistor. At least one of the second pixel and the third pixel includes a light blocking pattern that overlaps at least one of the first transistor and the second transistor. The first bridge and the second bridge do not overlap or cross the light blocking pattern in a plan view.

Abstract: A liquid crystal display (LCD) including: a first electrode disposed on a first substrate; an insulating layer disposed on the first electrode; a second electrode disposed on the insulating layer, overlapping the first electrode, and including a plurality of branch electrodes; and a second substrate opposing the second substrate. Liquid crystal molecules of a liquid crystal layer disposed between the substrates are aligned to have pretilt angles in an alignment direction. The branch electrodes include a main branch portion forming a first angle with the alignment direction and a first center portion forming a second angle with the alignment direction, respectively. The branch electrodes include an outermost branch electrode, and the outermost branch electrode includes the main branch portion forming a first angle with the alignment direction and a second center portion forming a fourth angle with the alignment direction.
