Abstract

A thin film transistor ('TFT') array panel is provided, which includes: first and second gate lines transmitting gate signals to adjacent pixel rows and disposed adjacent to each other, a data line insulated from the first and the second gate lines and the data line; a first thin film transistor connected to the first gate line and the data line and including a first drain electrode overlapping the second gate line; a second TFT connected to the second gate line and the data line, disposed opposite the first TFT with respect to the data line, and including a second drain electrode overlapping the first gate line; a first pixel electrode connected to the first drain electrode and overlapping the second gate line; and a second pixel electrode connected to the second electrode and overlapping the first a gate line.

Description

technical field [0001] The invention relates to a thin film transistor array panel. Background technique [0002] The general structure of the LCD includes a liquid crystal (LC) layer between an upper panel provided with a common electrode and a lower panel provided with pixel electrodes. The molecular orientation of the LC layer is changed by an electric field generated by different voltages applied to the common electrode and the pixel electrode, thereby adjusting light transmittance to display a desired image. [0003] The lower panel includes: gate lines (i.e., scanning lines); data lines (i.e., image signal lines); thin film transistors (TFTs), which are provided on each pixel and connected to the gate lines and data lines; pixel electrodes, connected to TFT. [0004] The passivation layer disposed on the lower panel is made of an organic material having a low dielectric constant to increase the aperture ratio of the LCD. For example, the aper...
