Liquid crystal display panel with ultra-narrow lower frame and manufacturing method thereof

Abstract

The embodiment of the invention discloses a liquid crystal display panel with an ultra-narrow lower frame. The liquid crystal display panel comprises a TFT array substrate, a CF substrate and a liquid crystal layer arranged between the TFT array substrate and the CF substrate, wherein the TFT array substrate comprises a substrate body, the substrate body comprises an active display area in the middle and peripheral area on the outer side of the active display area, at least one part of a lower frame area of the peripheral area extends out of the CF substrate, a pattern is etched on the lower frame area of the substrate body, an insulation layer is arranged on the pattern, the upper side of the insulation layer is etched to form a plurality of LCD conductive bonding pads, a plurality of via holes are formed in the insulation layer, and each LCD conductive bonding pad on the upper side of the insulation layer is electrically connected with the pattern etched on the lower frame area of the substrate body of the TFT array substrate through one via hole. The invention further discloses a corresponding manufacturing method. When the embodiment of the invention is implemented, the ultra-narrow lower frame of the liquid crystal display panel is achieved.

Description

technical field [0001] The invention relates to the display field, in particular to a liquid crystal display panel with an ultra-narrow lower frame and a manufacturing method thereof. Background technique [0002] The liquid crystal display panel has an active area and a peripheral circuit area. A plurality of pixels are arranged in the effective display area to form a pixel array, and a peripheral circuit is provided in the peripheral circuit area. Each pixel includes a thin film transistor and a pixel electrode connected to the thin film transistor, and each pixel is surrounded by two adjacent scanning lines and two adjacent data lines. Usually, these scan lines and data lines extend from the effective display area to the peripheral circuit area, and are electrically connected to the driver IC (drive IC) through the peripheral circuit. Generally speaking, the driver chip has a specific size design, and the peripheral circuits are concentrated from the end connecting the ...

AI Technical Summary

Problems solved by technology

[0005] To sum up, it can be seen that many design components need to be arranged on the glass substrate of the TFT array substrate 2'. In this structure, the width of the lower frame is relatively long, which is difficult to reduce.
