发明名称 Active matrix liquid crystal display device with divisional common electrodes aligned with divisional regions of TFTs
摘要 A liquid crystal display device comprises a first substrate on which a plurality of thin-film transistors, a plurality of pixel electrodes respectively connected to the thin-film transistors, a plurality of gate lines for connecting gate electrodes of the thin-film transistors, and a plurality of drain lines for connecting drain electrodes of the thin-film transistors are arranged in a matrix pattern, a second substrate on which a plurality of divisional common electrodes which face the plurality of pixel electrodes are formed, and a liquid crystal material encapsulated by the first and second substrates and a sealing member, and interposed between the plurality of pixel electrodes and the plurality of divisional common electrodes. The matrix pattern on the first substrate is formed by a photolithograpy process comprising a step of divisionally exposing photoresist in a plurality of divisional regions by using a stepper. The plurality of divisional common electrodes have sizes corresponding to the divisional regions divisionally exposed by the stepper and are separated from one another.
