Color filter substrate and display panel using same

Abstract

The invention provides a colour filtering substrate and a display panel applying the same, capable of preventing a local transparent electrode from being electrically isolated, so as to maintain display quality of the display panel. The colour filtering substrate disclosed by the invention comprises a substrate, a colour filtering layer and a transparent electrode. The colour filtering layer is formed on the substrate. The transparent electrode is formed on the colour filtering layer, the transparent electrode comprises an electrode block and multiple pattern slit units, and the pattern slit units are independent and surround the electrode block. Each pattern slit unit comprises a main slit, the main slit comprises an end part, and the end part comprises an end face. Projection along the normal direction of the end face is not overlapped with the end face of the end part of another most closet pattern slit unit.

Description

technical field [0001] The present invention relates to a color filter substrate and a display panel using the same, in particular to a color filter substrate with a slit structure and a display panel using the same. Background technique [0002] Please refer to figure 1 (Known technology), which shows a top view of a color filter substrate of a conventional liquid crystal display panel. The color filter substrate 10 of a conventional multi-domain alignment liquid crystal cell includes a color filter layer 20 and a transparent electrode 12 . The transparent electrode 12 covers the color filter layer 20 . The transparent electrode 12 has several pattern slit units 14 , and the color filter layer 20 is exposed from the pattern slit units 14 . Each pattern slit unit 14 includes two main slits 16 and several branch slits 18, the common one is that the two main slits 16 are in a cross-orthogonal shape, and the several branch slits 18 are at an oblique angle to the two main sli...

Problems solved by technology

[0003] However, in the process of manufacturing the color filter substrate 10, there will be multiple washing and thermal baking processes. Since the color filter layer 20 is easier to absorb water, and the thermal expansion coefficients of the color filter layer 20 and the transparent electrode 12 are different, resulting in The color filter layer 20 swells or thermally expands and squeezes the transparent electrode 12 from the pattern slit unit 14, and this stress easily makes the thinner electrode bridge P between the adjacent two pattern slit units 14 (the two pattern slit units 14) cracks, especially at the end of the extension direction of the main slit 16, because the accumulated expansion stress of the main slit 16 is larger than that of other branch slits 18, and the stress is easily caused by the structure The end is released, and the minimum distance between the two pattern slit units 14 is between two adjacent main slits 16

When most of the cracks expand and connect into multiple full fracture surfaces, the electrode bridge P may be split to produce several electrically isolated blocks, and it is impossible to input voltage signals

As a result, the liquid crystal molecules corresponding to the electrode bridges P will lose control, resulting in a significant drop in display quality
