Problems solved by technology

However, if there is a slight deviation in the assembly of the two substrates, or when the panel is squeezed by an external force, the spacer is easy to slide, causing light leakage in the panel area, resulting in reduced contrast or abnormal color display.

Abstract

The invention relates to a liquid crystal display device. The liquid crystal display device is characterized by comprising a first substrate, a second substrate and a liquid crystal layer; the first substrate comprises a base material, at least one first lead arranged on the base material, an insulating layer covering the first lead, at least one second lead arranged on the insulating layer and a protection layer covering the second lead; the first lead and the second lead are vertical to each other; the protection layer is provided with at least one concave part positioned above the first lead, or the second lead, or an intervening position of the first lead and the second lead; the second substrate is parallel to the first substrate and comprises at least one spacer; the bottom of the spacer abuts against the concave part; and the liquid crystal layer is arranged between the first substrate and the second substrate. The liquid crystal display device has the advantage of simple and novel structure, and the cost for manufacturing the liquid crystal display device is low.

Description

technical field [0001] The invention relates to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] The liquid crystal display is mainly composed of a thin film transistor array substrate, a color filter substrate and a liquid crystal molecular layer arranged between the two substrates. Since the thickness and uniformity of the liquid crystal molecular layer will affect the characteristics of the display, such as display speed, viewing angle, brightness and contrast, a spacer is needed between the two substrates to maintain a certain distance. [0003] Generally speaking, the spacers can be disposed on the thin film transistor array substrate or the color filter substrate. For example, it may be interspersed spherical spacers. However, if the assembly of the two substrates deviates slightly, or when the panel is squeezed by an external force, the spacer is easy to slide, resulting in regional light leakage of the panel, resulti...
