The application discloses a color filter substrate, an array substrate, a display panel and a display device. The color filter substrate comprises a first base substrate and a plurality of pixel units provided above the first base substrate, each of the pixel units comprising color filters of various colors; from a pixel unit close to a first side of the first base substrate towards a pixel unit close to a second side of the first base substrate opposite to the first side, a ratio of an area of a color filter of a specific color to that of any one of color filters of other colors is increased gradually. In the application, the color filter of the specific color is able to compensate for the color shift of the light guide plate, alleviating the color shift of the display device, and thereby improving the image quality of the display device.

The present disclosure provides a light concentrating film and a display device. The light concentrating film has a planar shape, and includes multiple light concentrating units which are connected to each other so as to concentrate the incident light on a light incoming side of the light concentrating film at the light outgoing side of the light concentrating film. The display device of the present disclosure includes a display panel and the light concentrating film of the present disclosure, and the light outgoing side of the light concentrating film faces a light incoming side of the display panel.

Light concentrating film and display device

A display device includes a display panel. A light-guide film is attached to a light-incident surface of the display panel. The light-guide film includes a light reflecting layer, a light exiting layer between the light reflecting layer and the display panel, and waveguide parts situated between the light reflecting layer and the light exiting layer. The light exiting layer has exit openings at positions facing each waveguide part, with each exit opening also facing a sub-pixel unit in the display panel. The display device also includes a light source. An end of each waveguide part is in communication with the light source. The light-guide film replaces a conventional backlight unit such that a thinner design for the display device is possible.
