ABSTRACT:
A liquid crystal display unit includes a first and a second substrate. A plurality of tiny projections are formed on the first substrate in a scattered arrangement. The tiny projections each have a generally semi-spherical configuration. Top portions of the projections each having a convexly curved surface are contacted with the second substrate, thereby a gap for filling a liquid crystal being formed between the first substrate and the second substrate. The tiny projections are formed by projecting a laser beam to the first substrate.
