Abstract
In the liquid crystal display device and the method of manufacturing the same, the pixel electrodes 32 and the projection pattern 35 are formed on the TFT substrate 30 side, and surfaces of the pixel electrodes 32 and the projection pattern 35 are covered with the vertical alignment film 36. Also, the opposing electrode 44 and the projection pattern 45 are formed on the CF substrate 40 side, and surfaces of the opposing electrode 44 and the projection pattern 45 are covered with the vertical alignment film 46. Then, the TFT substrate 30 and the CF substrate 40 are arranged such that top end portions of the projection pattern 45 on the CF substrate 40 are brought into contact with the TFT substrate 30. Then, the liquid crystal 49 having the negative dielectric anisotropy is sealed between them. 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.
