ABSTRACT:
A predetermined amount of adhesive is dropped on microlenses formed on a first transparent substrate, a second transparent substrate is mounted thereon and one of the first and second transparent substrates is rotated to provide a thin and uniform adhesive layer. Later the adhesive is cured and integrated in a thin film transistor substrate, to which liquid crystal is filled to obtain a liquid crystal panel. The distance D between the microlenses and the second transparent substrate is: 0<D.ltoreq.1 (.mu.m), and the parallel precision between the first and second transparent substrates is no more than 1 .mu.m. As the thickness of the adhesive layer can be thin and uniform, a liquid crystal panel having pixels with high numerical aperture and less display nonuniformity can be obtained.
