Problems solved by technology

[0005] However, because the touch display panel 100 of the prior art manufactures the main spacer 128 and the sensing spacer 129 between the transparent electrode 126 and the color filter layer 124 at the same time, the main spacer 128 is easy to be caused by the process. Pure substance or defect (defect), and the phenomenon of short circuit with the transparent conductive layer 112 on the thin film transistor array substrate 110, such as Figure 1A The short circuit S marked in , causing the touch display panel 100 to produce Figure 1B Line defect defects as shown, or as Figure 1C The defective point defects shown in the figure will reduce the yield rate or sensitivity of the touch display panel 100, thereby affecting the touch control effect or the overall display quality of the touch display panel.

Abstract

The invention provides a touch control display panel, a color filter substrate and a manufacturing method thereof. The method includes the following steps: first, a substrate is provided which has a plurality of pixel regions and the pixel regions are divided into a plurality of a first pixel regions, a plurality of second pixel regions and a plurality of third pixel regions; then forming a firstfilter layer in the first pixel region and some parts of the first region have pre-determinated regions of a main spacer; then a second filter layer is formed in the pre-determinated regions of the main spacer and the second pixel region and a third filter layer is formed in the third pixel region and the three filter layers from a color filter layer; then a sensing spacer is formed at parts of the color filter layers and an electrode layer is formed to cover the color filter layer and the sensing spacer; then a main spacer is formed at the electrode layer of the pre-determinated regions of the main spacer and a height difference is formed between the electrode layers of the main spacer and the sensing spacer so as to form a sensing gap.

Description

technical field [0001] The present invention relates to a display panel, a color filter substrate and a manufacturing method thereof, and in particular to a touch display panel with higher yield, a color filter substrate and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communications and information home appliances, many information products have been replaced by traditional input devices such as keyboards or mice in order to achieve more convenience, smaller volume and more humanization. Change to using a touch display panel (Touch Panel) as an input device, among which the touch-sensitive liquid crystal display device is the most popular product today. [0003] Figure 1A A schematic partial cross-sectional view of a touch display panel in the prior art is shown. Please refer to Figure 1A The touch display panel 100 is mainly composed of a thin film tra...
