A liquid crystal display with two insulating substrates. A first insulating substrate has crossing signal lines, a pixel electrode, and a drain electrode electrically connected to the pixel electrode through a contact hole. A spacer is formed on the first signal line of the first insulating substrate, and is wider at a first portion close to the first insulating substrate than at a second portion close to the second insulating substrate, and the drain electrode comprises a first portion and a second portion extending in a different direction with respect to the first portion.

A thin film transistor array substrate is provided with a gate line assembly, a data line assembly, and thin film transistors. The data line assembly crosses over the gate line assembly while defining pixel regions. A pixel electrode is formed at each pixel region. A color filter substrate is provided with a black matrix, and color filters of red, green and blue are formed at the black matrix at the pixel regions. An overcoat layer covers the color filters, and a common electrode is formed on the overcoat layer with an opening pattern. The thin film transistor array substrate, and the color filter substrates face each other, and a liquid crystal material is injected between the thin film transistor array substrate, and the color filter substrate. The blue color filter has a thickness smaller than the red color filter or the green color filter such that the liquid crystal cell gap at the blue color filter is larger than the liquid crystal cell gap at the red or green color filter.

Liquid crystal display and a method for fabricating the same

In a method of fabricating a thin film transistor array substrate, a black matrix with horizontal and vertical portions is first formed on a substrate with an opaque conductive material. A gate line assembly is formed on the black matrix, and buffer layers are formed between the separate portions of the black matrix. A gate insulating layer, a semiconductor layer, and an ohmic contact layer are sequentially deposited onto the substrate. And a data line assembly is formed on the ohmic contact layer. The ohmic contact layer exposed through the data line assembly is etched, and a protective layer is deposited onto the substrate. The protective layer, the gate insulating layer, and the semiconductor layer are patterned to form contact holes and opening portions exposing the insulating layer at pixel areas. The peripheral portions of the black matrix are also exposed through the opening portions. An indium tin oxide layer is deposited onto the substrate, and patterned to form pixel electrodes, subsidiary gate pads and subsidiary data pads that are connected to the drain electrodes, the gate pads and the data pads through the contact holes. Buffer conductive layers are formed at the same plane as the data line assembly or the pixel electrodes while being positioned over the semiconductor pattern between the neighboring data lines. Opening portions may be formed at a common electrode of the color filter substrate over the semiconductor pattern.
