Abstract: A display panel includes an upper display substrate including a first pixel area, a second pixel area, a third pixel area, and a light blocking area surrounding the first, second, and third pixel areas and a lower display substrate including a light emitting element. The upper display substrate includes a base substrate, a first bank overlapping the light blocking area and disposed on the base substrate, a second bank overlapping the light blocking area and disposed on the base substrate, a bridge bank disposed on the base substrate between the first bank and the second bank, and an organic material pattern at least a portion of which is disposed on the bridge bank forming a column spacer. The display panel has improved reliability.

Abstract: A liquid crystal display includes a gate line and a data line disposed on a substrate, a reference voltage line aligned with the data line, and a plurality of pixels arranged substantially in a matrix form. In such a liquid crystal display, each pixel includes a first sub-pixel, a second sub-pixel, and a driving unit electrically connected to the gate line, the data line and the reference voltage line. In such a liquid crystal display, one reference voltage line is disposed between two adjacent pixels.
