Disclosed is a liquid crystal display device improved transmittance and aperture ratio. The liquid crystal display device comprises a lower substrate, an upper substrate facing the lower substrate, and a liquid crystal interposed between the lower and upper substrate. A gate bus line and a data bus line is formed on the lower substrate in a matrix arrangement to define unit cell region. A thin film transistor is located near intersection of the gate bus line and the data bus line, for switching a signal inputted from the data bus line according to voltage applied to the gate bus line. A counter electrode is located inside unit cell region, for driving the liquid crystal, has a plurality of branches arranged parallel to each other and separated by a selected distance. A pixel electrode is connected to the thin film transistor to drive the liquid crystal together with the counter electrode and includes a plurality of slots for exposing the branches of the counter electrode. The counter electrode and the pixel electrode are formed out of a transparent conductive material. Also, the counter electrodes and the pixel electrodes are electrically insulated.
