LIQUID CRYSTAL DISPLAY

摘要

PURPOSE: A liquid crystal display for improving aperture ratio and transmittance ratio is provided to improve the transmittance ratio of the liquid crystal display and improve visibility of the display characteristic. CONSTITUTION: A liquid crystal display for improving aperture ratio and transmittance ratio includes a substrate, a common voltage line(178), a pixel electrode(191), a thin film transistor, a second thin film transistor, a third thin film transistor, and a fourth thin film transistor. The common voltage line delivers the common voltage formed on the substrate. The pixel electrode includes the first sub-pixel electrode and the second sub-pixel electrode formed on the common voltage line. The thin film transistor is connected to the first sub-pixel electrodes. The thin film transistor includes a first gate electrode, a first source electrode and a first drain electrode. A fourth thin film transistor is connected to the second sub-pixel electrodes.
