- the size and the number of contact hole capacities are proportional to the decrease in the thickness of the polyimide (PI) film, that is, the more contact holes, the larger the contact holes, the more the thickness of the PI film is reduced, and the contact holes are
- the number is proportional to the number of pixels.
- the reduction in the thickness of the PI film caused by the contact holes is not significant and does not cause significant disadvantages; however, at high resolutions greater than 1700 PPI, for example A contact hole of 1.5 ⁇ m deep causes a large decrease in the thickness of the PI film, such as from 800 ⁇ to 450 ⁇ , and an excessively thin ruthenium film causes an afterimage of an image displayed by the liquid crystal device, and a problem of reduced image contrast.
- the prior art method In order to avoid the problem of the reduction of the thickness of the ruthenium film, the prior art method generally increases the proportion of ruthenium in the mash, for example, the proportion of ruthenium in the sputum coated in the FFS TFT substrate is generally 5%-6.5%, slightly Higher than the proportion of the sputum coated in the TN TFT substrate, however, the ratio of sputum is generally difficult to be higher than 6.5%. If the proportion of bismuth in the mash is too high, the sputum is too viscous, causing sputum The problem of uneven coating. Therefore, the conventional method for the high-resolution TFT substrate cannot effectively avoid the problem caused by the reduction of the thickness of the ruthenium layer. Summary of the invention
