Embodiment Construction

[0036] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0037] The present invention aims at the limited space for placing the frame glue in the existing liquid crystal display panel. Since the gold ball and the insulating glue part overlap, the width of the glue here is increased. When forming the frame glue, the frame glue is easy to overflow to the cutting line or Technical problem with display area. The present inventi...

Abstract

The invention provides a liquid crystal display panel which comprises a display screen body. The display screen body comprises a thin film transistor substrate, a color film substrate, a liquid crystal layer and frame glue, wherein the liquid crystal layer and the frame glue are arranged between the thin film transistor substrate and the color film substrate. A conductive pad is arranged on the thin film transistor substrate, a common electrode is arranged on the color film substrate, and a conductive part which is electrically connected with the conductive pad and the common electrode is arranged on the side part of the display screen body. The common electrode is electrically connected with the conductive bonding pad on the outer side of the display screen body through the conductive part; therefore, a signal on the thin film transistor substrate does not need to be conducted to the color film substrate by a gold ball via the conductive bonding pad, the gold ball does not need to becoated, the technological process is simplified, the space occupied by the gold ball is saved, the frame glue is prevented from overflowing to the cutting line or the display area when the frame glueis formed, and a narrower bezel of the liquid crystal display panel can be achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a preparation method thereof. Background technique [0002] At present, the TFT-LCD liquid crystal display screen generally seals the TFT substrate and the CF substrate by a frame glue. The frame glue is generally composed of insulating glue and gold glue, in which the insulating glue is made by mixing a certain proportion of spacers, and the gold glue is made by mixing a certain amount of conductive gold balls. The insulating glue is coated around the display area to form a closed loop, which mainly plays a supporting role to maintain the uniformity of the thickness of the surrounding box; the gold glue is coated on the conductive pad on the TFT substrate in a dotted manner, so that the signal on the TFT substrate passes through the conductive pad. The gold balls on the pad conduct to the CF substrate. [0003] However, on products with narr...
