Embodiment Construction

[0032] As mentioned in the background art, the liquid crystal filling efficiency of the existing liquid crystal display panel is low, which easily causes problems such as uneven liquid filling and bubbles. The inventors have found that the cross-sectional area of ​​the liquid filling opening can be increased by increasing the distance between the CF substrate and the TFT array substrate in the liquid filling opening area, so as to promote the flow of liquid crystal from the filling opening to the inside of the liquid crystal display panel, thereby improving the filling liquid of the liquid crystal. efficiency.

[0033] Based on this, the present invention provides a liquid crystal display panel, including a CF substrate, a liquid crystal layer and a TFT array substrate arranged in sequence, to overcome the above-mentioned problems in the prior art, including:

[0034] Located between the CF substrate and the TFT array substrate, and connecting the liquid crystal display panel ...

Abstract

The invention provides a liquid crystal display panel. The liquid crystal display panel comprises a liquid filling opening which is located between a CF (Color Filter) substrate and a TFT (Thin Film Transistor) array substrate so that the outside of the liquid crystal display panel is communicated with an internal liquid crystal layer, wherein the space between the CF substrate and the TFT array substrate which are located in the region of the liquid filling opening is greater than the space between the CF substrate and the TFT array substrate which are located in other regions so that the cross sectional area of liquid crystals flowing through the liquid filling opening is greater than the cross sectional area of liquid crystals flowing through the other regions, and therefore, the flowing of the liquid crystals from the filling opening to the interior of the liquid crystal display panel, the filling efficiency of the liquid crystals is improved, and on the basis of the improvement of the filling efficiency, the problem of bubbles caused by uneven liquid filling and the like can be reduced; as a result, the quality of the liquid crystal display panel is improved and the production cost of the same is reduced.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, relates to a liquid crystal display panel. Background technique [0002] With the development of social informatization, people pay more and more attention to thin, light and portable display devices, among which TFT (Thin Film Transistor, Thin Film Transistor) liquid crystal display is the most concerned. [0003] Such as figure 1 As shown, the existing TFT liquid crystal display panel includes a CF (ColorFilter, color filter) substrate 1, a liquid crystal layer 2 and a TFT array substrate 3, and the dotted line part is an opening for liquid crystal filling, wherein the TFT array substrate 3 is from the bottom Upwards include: glass substrate 30, TFT array layer 31, common electrode 32 and pixel electrode 33, and there is a passivation layer between TFT array layer 31 and common electrode 32, between common electrode 32 and pixel electrode 33 and pi...
