The gate transmitting member includes a gate line and a gate electrode. A data transmitting member is disposed on the first substrate. The data transmitting member includes a data line, a source electrode, and a drain electrode. A pixel electrode is disposed in a pixel area. The pixel electrode is connected to the source electrode.

Abstract: A display apparatus includes a pixel connected to a data line. The pixel includes a first pixel electrode and a second pixel electrode spaced apart from the first pixel electrode in an extension direction of the data line. The second pixel electrode includes first to fourth stem portions. The third and fourth stem portions are further from the first pixel electrode than the first and second stem portions in the extension direction. The first and second stem portions are connected to one another to form a “V”-shaped structure. The third and fourth stem portions are connected to one another to form an inverted “V”-shaped structure.
