Abstract

An object of the present invention is to provide a liquid crystal display, which can surely perform an instillation process used when liquid crystal is sealed between substrates in a cell process, and a fabrication method thereof. A liquid crystal display comprises a sealing material made of a photo-curing type material which seals liquid crystal sandwiched between substrates, and a shading film having a shading area which overlays a red-colored layer transmitting red light, a green-colored layer transmitting green light and a blue-colored layer transmitting blue light, wherein only the blue-colored layer is formed in an area of the shading film contacting with the sealing material and the photo-curing type material of the sealing material is structured to have a light reactive area for a wavelength of blue color band.

Claims2

Dependent claims

A liquid crystal display comprising:

a sealing material made of a photo-curing type material sealing liquid crystal sandwiched between two substrates, said sealing material being formed at an external peripheral portion of a display area of the substrates, and having a portion overlapping with a shading film when viewed from a direction vertical to the substrates, said shading film being formed on a surface of one of the two substrates;
a structure sandwiched between the shading film and a surface of the other of the two substrates and formed at an area between the sealing material and the display area, said structure shading ultraviolet light;
a resistive resin layer including a concavo-convex structure having inclined surfaces and formed in an area under the sealing material in a direction of a width of the sealing material on the surface of the other of the two substrates;
and
a light-reflection layer for curing the sealing material formed on the concavo-convex structure to have a concavo-convex shape corresponding to the concavo-convex structure.
