Description
Technical field
The present invention relates to rub cloth and LCD (LCD), and especially relate to friction cloth, its manufacturing method and apparatus of a kind of liquid crystal that is used to align and utilize it to make the method for LCD.
Background technology
Usually, the LCD device utilizes the electrooptics characteristic displayed image information of liquid crystal.Some LCD devices transmitted ray when electric field is not applied on the liquid crystal.And some LCD devices stop light when electric field is not applied on the liquid crystal, and when electric field is applied on the liquid crystal transmitted ray.
Some LCD devices stop light when electric field is not applied on the liquid crystal, and this LCD device transmitted ray when electric field is applied on the liquid crystal.
In order to make the accurate transmission of light cross liquid crystal, the light that can see through liquid crystal should be provided to liquid crystal on the liquid crystal after consistent direction alignment equably again.The alignment of liquid crystal is by means of carrying out homogeneous thin film, and the light that can see through liquid crystal can obtain by polaroid.
To homogeneous thin film is polyimide film layer.When will be to homogeneous thin film during, on to homogeneous thin film, form the alignment groove against friction cloth towards the friction of consistent direction.The alignment of liquid crystal is carried out by means of the alignment groove.Friction cloth twines around the excircle of friction roller, and the friction roller of alignment groove by will having friction cloth is against friction is formed in the homogeneous thin film to homogeneous thin film.
Below, with reference to the manufacture process of Figure 1A to 1F description friction cloth.The term that is referred to herein as " friction cloth " fabric represents to have length and the cloth that is shorter than the width of length.
