Abstract
A liquid crystal display and a method for manufacturing the same are provided. An orientation film orientation-processed by a non-rubbing method using a polymer is formed on the respective opposing surfaces of first and second substrates. The first and second substrates on which the orientation films are formed are sealed to form a space, and then liquid crystal is injected into the space. A liquid crystal cell into which the liquid crystal has been injected is heated, and an ultraviolet ray of a predetermined wavelength is irradiated on the liquid crystal cell for a predetermined period of time, thereby forming the liquid crystal display. Thus, the pretilt angle can be increased.
Claims6
A method for manufacturing a liquid crystal display, said method comprising the steps of:
- (a) coating an orientation film on the respective opposing surfaces of first and second transparent substrates;
- (b) orientation-processing said orientation films using a non-rubbing method;
- (c) injecting and sealing liquid crystal between said orientation films to thereby produce a liquid crystal cell;
- (d) heating said liquid crystal cell to a predetermined temperature;
- and
- (e) irradiating an ultraviolet ray on said liquid crystal cell.
