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.

Claims (8)

1. A method of fabricating a liquid crystal display having processes of dropping liquid crystal at a plurality of positions on one of two substrates, attaching the one of the substrates with the other substrate via a sealing material made of a photo-curing type material, and curing the sealing material by irradiating light thereon, the method comprising:

forming a horizontal alignment film for aligning molecules of the liquid crystal in a direction parallel to the substrates, on opposing surfaces of the two substrates;

forming a vertical alignment film for aligning the molecules of liquid crystal in a direction perpendicular to the two substrates, on the horizontal alignment films in an area adjacent the sealing material;

irradiating the light after perpendicularly aligning the molecules of the liquid crystal adjacent to the sealing material.

2. A method of fabricating a liquid crystal display having processes of dropping liquid crystal at a plurality of positions on one of two substrates, attaching the one of the substrates with the other substrate via a sealing material made of a photo-curing type material, and curing the sealing material by irradiating light thereon, the method comprising:

forming a first electrode electrically isolated from a pixel electrode on one of opposing surfaces of the two substrates adjacent to the sealing material;

forming a second electrode electrically isolated from a common electrode on other of opposing surfaces of the two substrates adjacent to the sealing material; and

irradiating the light on the sealing material after aligning molecules of the liquid crystal in the area adjacent the sealing material perpendicularly to the substrates by applying a voltage between the first and second electrodes.
