Abstract
A liquid crystal display comprising: a lower substrate having a plurality of gate bus lines being parallel each other and data bus lines being parallel each other to define pixels together with the gate bus lines, a thin film transistor provided at each intersection of the data bus line and the gate bus line, a pixel electrode formed in the pixel and connected to the thin film transistor, and a counter electrode formed in the pixel and forming electric field together with the pixel electrode; an upper substrate opposed to the lower substrate to be separated apart; a liquid crystal layer interposed between the lower substrate and the upper substrate, and homeotropic alignment layers formed on the lower substrate and the upper substrate; wherein, the pixel is divided into a plurality of electric field-formed spaces by the counter electrode and the pixel electrode, and the electric fields formed in the respective spaces are formed as diagonal lines with respect to the gate bus lines and the data bus lines thereby making symmetries with those electric fields formed at adjacent spaces.
