Manufacturing device for liquid crystal display panel and manufacturing method of the same

Abstract

A liquid crystal panel manufacturing device and liquid crystal panel manufacturing method, capable of manufacturing liquid crystal panel with excellent performance and high yield by inhibiting ultraviolet irradiation from a wavelength range possibly causing influence on the liquid crystal panel performance. The provided liquid crystal panel manufacturing device comprises a processing chamber (50)for processing to-be-processed substrate (10) sealed with liquid crystal (17) containing light responsiveness material (18); a plurality of lamps (52) disposed in the processing chamber (50), irradiating ultraviolet towards the to-be-processed substrate (10) to lead the light responsiveness material (18) for reaction, in order to form orientation part (21, 22) inside the to-be-processed substrate(10); and filters (53) aligning to the lamps (52), and at least inhibiting the ultraviolet transmission of which wavelength ranges from 320 to 360 nm.

Description

technical field [0001] The present invention relates to a liquid crystal panel manufacturing device and a liquid crystal panel manufacturing method using the liquid crystal panel manufacturing device. Background technique [0002] Liquid crystal panels have advantages such as high display quality, thinner thickness, and lower power consumption, so they are used in various applications. Especially in recent years, as the demand for large liquid crystal devices such as liquid crystal televisions has increased, performance requirements for liquid crystal panels have also increased. [0003] In order to obtain a high-performance liquid crystal panel, alignment control of an alignment film for aligning a liquid crystal in a predetermined direction is important. Conventionally, the "rubbing method" of rubbing the alignment film with a cloth or the like has generally been used. However, if the rubbing method is used, there are problems such as dirt adhesion due to dust falling, a...

Problems solved by technology

[0005] However, due to the irradiation conditions and wavelength range of ultraviolet rays, etc., the performance and yield of the manufactured liquid crystal panel will be affected.

Especially in the liquid crystal panel manufacturing process implemented by the photo-alignment method, if more ultraviolet light below a certain wavelength range is irradiated, it will cause a significant decrease in the performance and yield of the manufactured liquid crystal panel.
