Active matrix liquid crystal display device

A liquid crystal display device comprises a first substrate (110) on which a plurality of thin-film transistors (120), a plurality of pixel electrodes (170) respectively connected to the thin-film transistors, a plurality of gate lines (GL) for connecting gate electrodes of the thin-film transistors, and a plurality of drain lines (DL) for connecting drain electrodes of the thin-film transistors are arranged in a matrix pattern, a second substrate (210) on which a plurality of divisional common electrodes (240a, 240b, 240c, 240d) which face the plurality of pixel electrodes are formed, and a liquid crystal material encapsulated by the first and second substrate and a sealing member (300), 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.
