Liquid crystal display panel, thin film transistor substrate and manufacturing method thereof

Abstract

The invention provides a liquid crystal display panel, a thin-film transistor substrate and a manufacturing method thereof. The liquid crystal display panel comprises a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate comprises a first base, thin-film transistors arranged on the first substrate, a passivation layer covering the thin-film transistors, a pixel electrode electrically connected with the thin-film transistors, a common electrode layer insulated from the pixel electrode, a common electrode wire electrically connected with the common electrode layer and a black matrix. The common electrode layer and the pixel electrode generate liquid crystal molecules parallel to an electric field driving liquid crystal layer to rotate in a plane, the common electrode wire and the black matrix are arranged in a superposed manner and are corresponding in shape and position. The liquid crystal display panel is high in aperture ratio.

Description

technical field [0001] The invention relates to a liquid crystal display panel, a thin film transistor substrate and a manufacturing method thereof. Background technique [0002] A liquid crystal display panel generally includes a thin film transistor substrate, a color filter substrate disposed opposite to the thin film transistor substrate, and a liquid crystal layer sandwiched between the two substrates. Usually, an opaque thin film transistor and a driving circuit are arranged on the thin film transistor substrate, and a black matrix is ​​arranged on the color filter substrate, wherein the black matrix needs to be arranged corresponding to the thin film transistor and the driving circuit, so that the thin film transistor and the driving circuit The driving circuit is shielded to avoid light leakage. However, since the thin-film transistor substrate and the color filter substrate are manufactured independently and then bonded together through frame glue, when the thin-fi...

Problems solved by technology

However, since the thin-film transistor substrate and the color filter substrate are manufactured independently and then bonded together through frame glue, when the thin-film transistor substrate and the color filter substrate are combined, the black matrix, the thin-film transistor and the driving circuit Alignment deviations are prone to occur between them, resulting in a decrease in the aperture ratio of the LCD panel
