PURPOSE: A liquid crystal display device is provided to prevent a distortion electric field by a side electrode from being disturbed by data lines or gate lines by forming the side electrode between two neighboring pixel electrodes. CONSTITUTION: A liquid crystal display device is comprised of the first substrate(21), the second substrate(22), data lines, gate lines, thin film transistors(29), the first insulating layer(33), side electrodes(34), the second insulating layer(35), pixel electrodes(36), an opposite electrode(37), and a liquid crystal layer(38). The data lines and the gate lines, horizontally and vertically formed on the first substrate(21), divide the first substrate(21) into a plurality of pixel domains. The thin film transistors(29), respectively formed in the pixel domains, are composed of gate electrodes(23), a gate insulating layer, a semiconductor layer(25), an ohmic contact layer(26), and source/drain electrodes(27,28). The first insulating layer(33), formed on the whole of the first substrate(21) above the thin film transistors(29), has contract holes(32). The side electrodes(34), formed on the first insulating layer(33), are formed around the pixel domains so as to be overlapped with the thin film transistors(29), the data lines, and the gate lines(31). The second insulating layer(35) is formed on the whole of the first substrate(21) above the thin film transistors(29). The pixel electrodes(36), connected to the drain electrodes(28) through the contact holes(32), are respectively formed in the pixel domains above the second insulating layer(35). The opposite electrode(37) is formed on the second substrate(22). The liquid crystal layer(38) is formed between the first substrate(21) and the second substrate(22).
