Abstract
In a liquid crystal display device, the pixel electrodes and the projection pattern are formed on the TFT substrate side, and surfaces of the pixel electrodes and the projection pattern are covered with a vertical alignment film. Opposing electrode and a projection pattern are formed on the CF substrate side, and surfaces of the opposing electrode and the projection pattern are covered with a vertical alignment film. The TFT substrate and the CF substrate are arranged such that top end portions of the projection pattern on the CF substrate are brought into contact with the TFT substrate. Liquid crystal having negative dielectric anisotropy is sealed between the TFT and CF substrates. Accordingly, the step of scattering the spacers can be omitted, change in the cell thickness can be prevented, and the good display quality can be achieved.
