Patent ID: 8040478

Claim:
A manufacturing method of a liquid crystal display device comprising: a first step for forming at least one first projecting portion on a first substrate, and a first alignment film on the first substrate and the at least one first projecting portion; a second step for forming at least one second projecting portion on a second substrate which has a height larger than a height of the at least one first projecting portion and an has area of an upper surface of the at least one second projecting portion is larger than an area of an upper surface of the at least one first projecting portion, and for forming a second alignment film on the second substrate and the at least one second projecting portion; a third step for baking the first alignment film; and a fourth step for radiating polarized light containing ultraviolet rays to the first alignment film, wherein a film thickness “d 1 ” of the first alignment film on the at least one first projecting portion after the fourth step and a film thickness “d 2 ” of the second alignment film on the at least one second projecting portion satisfy a formula (1) and a formula (2): 0nm<d1<30nm (1) d2<d1 (2).
