Abstract
The present application discloses a liquid crystal display panel and a display device. In the liquid crystal display panel, a sub-pixel area includes a light-emitting area and a circuit area connected to the light-emitting area. Each of sub-pixel driving circuits is correspondingly disposed in a circuit area, and each of the sub-pixel driving circuits includes at least one thin film transistor. At least three sub-color resists of a same color resist are respectively arranged in at least three sub-pixel areas of a same pixel area. Colors of secondary color resists of the at least three sub-color resists arranged in the same pixel area are same.
