The invention relates to a color film substrate, a display panel and a preparation method of a color film substrate. A water absorption retaining wall and a frame adhesive layer are arranged in a frame area of the color film substrate, and the frame adhesive layer has water vapor blocking capacity and is arranged in the frame area, so water vapor can be reduced or even prevented from penetrating through the frame area to enter an effective display area; the water absorption retaining wall has the water vapor absorption capacity, so part of water vapor is inevitably absorbed by the water absorption retaining wall when the water vapor penetrates through the water absorption retaining wall, and the amount of the water vapor moving towards the effective display area is further reduced. At least one linear path penetrating through the frame area and entering the effective display area on the plane parallel to the light-transmitting substrate needs to penetrate through the frame glue layer and the water absorption retaining wall, so water vapor blocking and water vapor absorption are combined on the path where water vapor enters the effective display area, the protection grade of the light conversion material in the effective display area is improved, and reliability and quality of the color film substrate and the display panel are enhanced.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a display panel and a method for preparing the color filter substrate. Background technique [0002] In full-color display panels, blue light chips or UV light chips are usually used as the excitation light source, and light conversion materials such as QD (Quantum Dot, quantum dot) materials or phosphors are used to convert the wavelength of the light emitted by the excitation light source, thereby converting the blue light Or UV light is converted into red (R) green (G) blue (B) three colors to achieve full color. However, because the light-converting material is not resistant to water and oxygen, once external water vapor invades through the side of the display panel and reaches the light-converting material, it will cause the light-converting material to fail, thereby affecting the full-color performance of the display panel. Therefore, how to bloc...
