Abstract

A thin film transistor panel and a method of manufacturing the same are disclosed. The thin film transistor panel includes a thin film transistor including a drain electrode with an opening, and a transparent electrode contacts a portion of the opening.

Description

technical field [0001] The present invention relates to a liquid crystal display and a manufacturing method thereof. More particularly, the present invention relates to thin film transistor panels and methods of manufacturing the same. Background technique [0002] A liquid crystal display (LCD) is one of the most commonly used flat panel displays. The LCD includes a liquid crystal layer interposed between two panels having a plurality of electrodes, and the transmissivity of incident light is controlled by rearranging liquid crystal molecules of the liquid crystal layer by applying a voltage to the electrodes. [0003] A typical LCD includes a first panel in which a plurality of pixel electrodes are arranged in a matrix (hereinafter referred to as a "thin film transistor (TFT) panel") and a second panel in which a substrate is covered with single common electrode. [0004] In order to switch the pixel electrodes of the TFT panel, TFTs having gate electrodes, semiconducto...
