Abstract
In a liquid-crystal display element each individual liquid-crystal injection area is surrounded by a seal, and the overall liquid-crystal injection area is surrounded by an array substrate and an opposing substrate surrounded by an outer peripheral seal having an aperture and are adhered together, the aperture of the outer peripheral seal being sealed by a hole sealant, and the surface of at least one of the array substrate and the opposing substrate being polished with a polishing material, which is then removed, after which cutting along the aperture is done to separate the individual liquid-crystal injection areas, thereby facilitating the achievement of a thin liquid-crystal display element, while improving the quality and yield thereof.
Claims5
A method for manufacturing a liquid-crystal display element comprising:
- a first step of forming a plurality of liquid-crystal injection areas surrounded with a seal on an array substrate;
- a second step of adhering said array substrate on which overall said liquid-crystal injection areas being surrounded by an outer peripheral seal having an aperture and an opposing substrate;
- a third step of sealing said aperture of said outer peripheral seal using a hole sealant;
- a fourth step of polishing a surface of at least one of said array substrate and said opposing substrate using a polishing material;
- a fifth step of polishing an end surface of at least one of said array substrate and said opposing substrate, using a polishing material and removing said polishing material;
- and
- a sixth step of cutting said liquid-crystal injection areas along a virtual lines each formed between said apertures each provided on two of said outer peripheral seals, respectively, and each of said outer peripheral seals being oppositely arranged to each other.
