Claim:
1. A photo-alignment method, comprising: providing a top panel and a bottom panel; providing a mask plate for shielding the top panel and the bottom panel, and disposing a transparent section of the mask plate; emitting an ultraviolet along a first incident direction by the mask plate for exposing a top alignment film of the top panel and a bottom alignment film of the bottom panel; adjusting the transparent section of the mask plate; and emitting an ultraviolet along a second incident direction by the mask plate for exposing a top alignment film of the top panel and a bottom alignment film of the bottom panel; wherein, providing the top panel and the bottom panel comprises: dividing a high gray scale sub pixel at the bottom panel into a first high gray scale sub pixel section and a second high gray scale sub pixel section, wherein the first high gray scale sub pixel section is adjacent to the second high gray scale sub pixel section, and the first high gray scale sub pixel section and the second high gray scale sub pixel section are disposed along a long edge of a pixel, and dividing a low gray scale sub pixel at the bottom panel into a first low gray scale sub pixel section and a second low gray scale sub pixel section, wherein the first low gray scale sub pixel section is adjacent to the second low gray scale sub pixel section, and the first low gray scale sub pixel section and the second low gray scale sub pixel section are disposed along a long edge of a pixel; dividing a high gray scale sub pixel at the top panel into a first high gray scale sub pixel section and a second high gray scale sub pixel section, wherein the first high gray scale sub pixel section is adjacent to the second high gray scale sub pixel section, and the first high gray scale sub pixel section and the second high gray scale sub pixel section are disposed along a short edge of a pixel, and dividing a low gray scale sub pixel at the top panel into a first low gray scale sub pixel section and a second low gray scale sub pixel section, wherein the first low gray scale sub pixel section is adjacent to the second low gray scale sub pixel section, and the first low gray scale sub pixel section and the second low gray scale sub pixel section are disposed along a short edge of a pixel; and disposing the top panel and the bottom panel so that the top panel and the bottom panel being vertical to each other, wherein in the step of providing a mask plate for shielding the top panel and the bottom panel, and disposing a transparent section of the mask plate, the photo-alignment method further comprises: exposing a first transparent section of the mask plate and disposing the first transparent section of the mask plate corresponding to the first high gray scale sub pixel section of the bottom panel; a first shield plate of the mask plate shielding a second transparent section of a first opening; exposing a third transparent section of the mask plate and disposing the third transparent section of the mask plate corresponding to the first low gray scale sub pixel section of the bottom panel; a second shield plate of the mask plate shielding a fourth transparent section of a second opening; exposing a fifth transparent section of the mask plate and disposing the fifth transparent section of the mask plate corresponding to the first high gray scale sub pixel section of the top panel; a third shield plate of the mask plate shielding a sixth transparent section of a third opening; and exposing a seventh transparent section of the mask plate and disposing the seventh transparent section of the mask plate corresponding to the first low gray scale sub pixel section of the top panel; a fourth shield plate of the mask plate shielding an eighth transparent section of a fourth opening.
