Abstract: PURPOSE: To manufacture a liquid crystal display device which is free from light leakage and can form a high contrast, through a minimum number of manufacturing processes. CONSTITUTION: In order to obtain a cell gap Ga, a first projection 38A is formed in a black matrix 38 on an array substrate 12, and a second projection 50 is formed on a color filter substrate 13 by laminating a red color filter 46R, a green color filter 46G, and a blue color filter 46B each upon the other. Since the heights of the first and second projections 38A and 50 can be adjusted to, for example, half of the cell gap Ga, oriented films 40 and 50 can be rubbed surely. Therefore, liquid crystal molecules can be aligned surely, and the occurrence of light leakage can be prevented. Since no transparent spacer is required, in addition, the light leakage caused by the spacer does not occur. The projections 38A and 50 can be formed through the forming processes of the color filters 46 and black matrix 38 only.
