A pixel structure is disclosed. The pixel structure includes first transparent conductive films that are arranged on color-resists of a color filter substrate, and second transparent conductive films that are arranged on sub pixel regions of an array substrate and correspond to the first transparent conductive films. The first transparent conductive films are connected with one another. An area of each first transparent conductive film is larger than an area of a corresponding second transparent conductive film. The first transparent conductive film is provided with a groove on a part thereof beyond the second transparent conductive film. According to the present disclosure, a light transmittance of the pixel structure can be greatly improved.
