Abstract

Disclosed are a thin film transistor array panel and a liquid crystal display (LCD) device. The thin film transistor array panel comprises a plurality of gate lines, data lines, a plurality of pixel units and a multistage gate driving signal generation unit, wherein the plurality of gate lines and the data lines are perpendicular to each other. Each pixel unit comprises at least one thin film transistor, the gate lines are connected with a grid electrode of the thin film transistor, and the data lines are connected with a source electrode of the thin film transistor. The multistage gate driving signal generation unit is connected with the gate lines and is used for receiving a first grid driving control signal, a second grid driving control signal, a gate source signal and a negative voltage signal and supplying gate driving signals to the gate lines. The phase position of the first grid driving control signal is opposite to the phase position of the second grid driving control signal. By means of the thin film transistor array panel and the LCD device, a narrow frame of the thin film transistor array panel can be achieved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal manufacturing, in particular to a thin film transistor array panel and a liquid crystal display device. Background technique [0002] In a liquid crystal display (LCD) or other flat-panel displays with a similar structure, such as e-books, organic light-emitting diode flexible displays, etc., the gate lines are horizontally arranged as the row driving lines in the layout of the liquid crystal pixel array. [0003] Taking a thin film transistor liquid crystal panel (TFT-LCD) as an example, it displays images through a matrix of liquid crystal pixels. See figure 1 , figure 1 It is a structural diagram of a TFT-LCD panel in the prior art, including multiple sub-pixel units, multiple gate lines G1, G2...Gn, and multiple data lines D1, D2...Dm connected thereto. Each sub-pixel unit includes a thin film transistor (TFT), a storage capacitor, a liquid crystal capacitor, etc., and the gate of th...
