Problems solved by technology

However, the high-voltage lamps in the prior art have the problems of relatively short service life, high heat generation, and high price, so it is difficult to use them in actual production
In addition, the output of the high-voltage lamps in the prior art decreases sharply after being used for a certain period of time, and the tack time is long, so it is difficult to use in the actual oriented film processing process

Abstract

Disclosed are a stage rotation device and an optical orientation apparatus including same. The optical orientation apparatus according to one aspect of the present invention includes an optical irradiation unit, which has an electrodeless UV lamp which emits light by receiving microwaves and aligns liquid crystal elements in a certain direction by polarizing the light from the electrodeless UV lamp and irradiating an orientation film with the light, and the stage rotation device which is capable of changing the entry angle of the orientation film with respect to the irradiation direction of the optical irradiation unit.

Description

technical field [0001] The present invention relates to photo-alignment devices with microwave ultraviolet lamps (UV lamps). Background technique [0002] Usually, a liquid crystal display device forms a liquid crystal layer between two glass substrates, and on the inner surfaces of the two glass substrates, there are formed transparent electrodes that form an electric field for the liquid crystal layer, switching elements that turn on or off the power supply for the electric field, and display colors. The color filter (Color filter) and the orientation film for the orientation of the liquid crystal molecules, etc. Liquid crystal material is sealed between two glass substrates to manufacture a liquid crystal display element. The alignment film is formed by a resin layer such as polyimide resin coated on the substrate. After the alignment film is hardened, it is rubbed by a rubbing device to align the liquid crystal in a certain direction. [0003] Usually, both ends of the...
