It is straight.
The present invention provides a kind of light alignment method of display panel, by the exposure directions and array substrate that make array substrate
Flow direction it is vertical, and keep the exposure directions of opposite side substrate vertical with the flow direction of opposite side substrate, and the flow direction and array of opposite side substrate
The flow direction of substrate is vertical, in this way by array substrate and opposite side substrate in batch it is vertical form the display panel after, under the action of orientation,
One end will topple over liquid crystal molecule between array substrate and opposite side substrate towards the sub-pixel center of display panel when rotated,
In the active force by ITO fringe field, since the force direction of ITO fringe field is by edge towards sub-pixel list
The inside of member, thus when rotating liquid crystal molecule between array substrate and opposite side substrate one end towards the center of sub-pixel,
The rotation status of the liquid crystal molecule influence that is just not easily susceptible to fringe field active force in this way, makes it still in the rotation of maximum transmission
Turn state, to achieve the effect that eliminate periphery dark line, " Swastika " the type dark line generated in existing alignment technique is made to be changed into " ten "
Type dark line effectively improves the transmitance of display panel.Therefore, the light orientation side of a kind of display panel provided by the invention
Method can effectively change being changed without mask, do not change array substrate and opposite side substrate flow direction and under the premise of do not increase processing procedure
Kind display dark line, promotes transmitance, solves in existing smooth alignment technique, under the active force of ITO fringe field, edge
Liquid crystal molecule and the internal rotation angle of liquid crystal molecule it is different, can also generate dark line at edge, reduce display panel transmission
The problem of rate.
