Manufacturing method and device of a liquid crystal panel

Abstract

The invention provides a manufacturing method and device of a liquid crystal panel capable of performing the orientation of the liquid crystal panel in the short time, not resulting into reduced reliability. The liquid crystal including a UV reaction material is encapsulated on the liquid crystal panel (8) between two light-transparent substrates (glass substrates) on a first workpiece platform (3a). In the first step, while applying the voltage from a probe (4), the light with wavelength larger than that of the absorbing end of the liquid crystal (wavelength range of 320nm-360nm) irradiates a first light irradiating part (1). Then, the liquid crystal panel (8) is transported on a second workpiece platform (3b) using a workpiece transportation mechanism (5) and the light with wavelength shorter than that of the absorbing end of the liquid crystal (wavelength range of 300nm-320nm) irradiates a second light irradiating part (2), so as to perform the orientation of the liquid crystal. The lamp of the first step can use such as an iodine quasi molecule lamp and the lamp of the second step can use such as an XeCl quasi molecule lamp.

Description

technical field [0001] The present invention relates to a method of manufacturing a liquid crystal panel of the MVA (Multi-domain Vertical Alignment) method, and more particularly to a photoreactive liquid crystal that is oriented by applying a voltage and reacts with ultraviolet rays to cause polymerization. Substance materials are pre-enclosed between two glass substrates, and the liquid crystal panel is irradiated with ultraviolet rays to polymerize the ultraviolet reactive material, thereby forming an alignment film on the glass plate. The manufacturing method and manufacturing device of the liquid crystal panel. Background technique [0002] A liquid crystal panel is a structure in which liquid crystal is sealed between two light-transmitting substrates (glass substrates). A plurality of active elements (TFTs) and electrodes for liquid crystal driving are formed on one glass substrate, and an alignment film is formed on it. . A color filter, an alignment film, and a tr...

Problems solved by technology

[0009] In "Liquid Crystal Display Device and Its Manufacturing Method" described in Patent Document 3, it is shown that "in order not to degrade the liquid crystal, it is known that it is better to irradiate ultraviolet light in a short-wavelength region of less than 310 nm by using a filter." "However, if the intensity at the wavelength of 310nm is completely zero, it is difficult to obtain the desired liquid crystal alignment
