Problems solved by technology

[0007] In the actual product, it is found that the method of setting spacers on the auxiliary electrodes is used. Due to the large thickness of the spacers, it is easy to cause the transparent electrode to break, resulting in a decrease in yield, and the reflection of the auxiliary electrode, resulting in lateral light leakage. Problems such as low opening rate

Embodiment Construction

[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] Such as figure 1 As shown, the present invention provides a color filter substrate, which includes a transparent substrate 1, the transparent substrate 1 can be made of glass and other materials; the transparent substrate 1 is provided with a photoresist layer 2, and the photoresist layer 2 It includes at least a plurality of red photoresist units, a plurality of green photoresist unit layers and a plurality of blue photoresist units; of course, in order to enrich the display color and improve brightness, the color photoresist layer 2 may also include other color photoresist units.

[0041] The photoresist layer 2 is provided with a protective layer 3. The protecti...

Abstract

The invention relates to the field of display technology, in particular to a color filter substrate and a fabrication method and a display device thereof. The color filter substrate comprises a transparent substrate, and a photoresist layer, which at least comprises a plurality of red photoresist units, a plurality of green photoresist units and a plurality of blue photoresist units, is arranged on the substrate; a protective layer is arranged on the photoresist layer; a plurality of auxiliary electrodes are arranged on the protective layer, and the position of each auxiliary electrode corresponds to the joint between two neighboring photoresist units with different colors; a black matrix is arranged on the auxiliary electrodes and partially covers the auxiliary electrodes. Because the black matrix is arranged upon the auxiliary electrodes in the color filter substrate, lateral light leakage caused by the reflection of light by the auxiliary electrodes can be effectively reduced, the aperture ratio is increased, the thickness of spacers is reduced, and the yield of increased; meanwhile, the effect of reducing masks can be realized, so the cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method thereof, and a display device. Background technique [0002] At present, OLED (Organic Light-Emitting Diode, organic light-emitting diode) has gradually become the mainstream of display technology due to its high mobility and good uniformity, and the next-generation display technology AMOLED (Active Matrix Organic Light Emitting Diode, active matrix organic Light-emitting diode panels) are more sought after by users because of their advantages such as fast response, high contrast, and wider viewing angles. [0003] In actual production, WOLED (white OLED) combined with CF (color filter substrate) technology is an important development direction of AMOLED. Due to the advantages of high utilization rate of organic light-emitting materials, low requirements for the mask plate of the evaporated light-emitting sheet, and high aperture...
