Abstract

A thin film transistor substrate for a liquid crystal display, which can provide a required pixel discharging time, and a liquid crystal display comprising the same are disclosed. The thin film transistor substrate comprises a plurality of unit pixels arranged in an (m×n) matrix array, gate lines disposed one by one for every two unit pixels neighboring in a column direction, wherein one gate signal is simultaneously supplied to the two unit pixels via one gate line, data lines intersecting the gate lines, supplying data signals to the unit pixels in synchronization with the gate signals supplied via the gate lines wherein said data lines are arranged two by two between the unit pixels neighboring in a row direction and a thin film transistor TFT formed at each crossing portion of the gate lines and the data lines and transmitting the data signals to pixel electrodes in response to the gate signals.
