Abstract
A display panel is provided. A plurality of target sub-pixels of the display panel in a pixel arrangement direction, and located in a first area and adjacent to a second area have a same luminous color. The first area and the second area correspondingly correspond to a light color area and a dark color area in an electrical testing screen. In this way, when an alignment precision inspection technique is performed based on an electrical testing screen, luminous colors of sub-pixels affecting colors of border lines are same. Therefore, the border lines having different colors caused by photoresists having different colors do not occur.
