A color filter substrate includes a transparent substrate, a light-blocking layer, a color filter layer, a first cell gap maintaining member and a second cell gap maintaining member. The transparent substrate has a plurality of pixel regions. Each of the pixel regions includes first and second regions. The light-blocking layer is disposed over the transparent substrate. The light-blocking layer blocks light that leaks through boundaries of the pixel regions. The color filter layer is disposed over the transparent substrate. The color filter layer has a first thickness at the first region and a second thickness that is smaller than the first thickness at the second region. The first cell gap maintaining member is disposed at the first region. The second cell gap maintaining member is disposed at the second region. Therefore, a height difference between the main column spacer and the sub column spacer may be easily adjusted.

A liquid crystal display (LCD) having high luminance and color renditions is provided. The liquid crystal display includes a first insulating substrate, a gate line and a data line crossing each other on the first insulating substrate to define a pixel. First and second sub-pixel electrodes divide the pixel into two parts. A first switching element drives the first sub-pixel electrode and a second switching element drives the second sub-pixel electrode. A second insulating substrate faces the first insulating substrate. A color pattern is arranged on the second insulating substrate and overlaps the first sub-pixel electrode. A contrast pattern overlaps the second sub-pixel electrode.

In manufacturing a thin film transistor array substrate, a passivation film is formed over the transistors. A first photoresist pattern is formed over the passivation film, with a first portion partially overlying at least one source/drain electrode of each transistor and overlying each pixel electrode region, and with a second portion thicker than the first portion. The passivation film is patterned using the first photoresist pattern as a mask. The first photoresist pattern's first portion is removed to form a second photoresist pattern which protrudes upward around the pixel electrode regions. A transparent conductive film is formed with recesses in the pixel electrode regions. A masking pattern is formed over the transparent film in each pixel electrode region, the masking pattern's top surface being below a top of the transparent film. The transparent film is patterned using the masking pattern as a mask to form the pixel electrodes.

Method of manufacturing a thin film transistor array substrate

A liquid crystal display includes a conductive spacer that connects a common voltage line of an array substrate to a common electrode of an opposite substrate. The conductive spacer has a bar-like shape and extends along the common voltage line.

A method of driving gate lines is used to activate the gate lines by outputting output signals of stages to the gate lines. A first node is boosted up based upon a carry signal or the vertical start signal from a previous stage. A gate signal that is pulled up is outputted through an output terminal of a present stage based upon a first clock signal which is boosted up. An off-voltage is outputted through the output terminal of the present stage in response to an output signal from a next stage or the vertical start signal. The first node is discharged in response to the output signal from the next stage or a carry signal from a last stage. A positive ripple voltage at the first node is removed by providing a negative ripple voltage to the first node.
