Optical film and liquid crystal display utilizing the same
View Patent ↗An optical film includes an outer surface, a plurality of protrusions protruding from the outer surface and extending substantially parallel to a first axis, a plurality of grooves formed at neighboring protrusions; and two barrier members arranged at opposite sides of the optical film substantially parallel to a second axis. The first axis is substantially perpendicular to the second axis. The two barrier members prevent each slot from communicating with the exterior of the optical film continuously.
1. An optical film, comprising: an outer surface; a plurality of protrusions protruding from the outer surface and extending substantially parallel to a first axis; a plurality of grooves formed between neighboring protrusions; and two barrier members arranged at opposite sides of the optical film substantially parallel to a second axis, which is substantially perpendicular to the first axis; and preventing each groove from communicating with the exterior, wherein the barrier members are integrally formed with the optical film.
2. The optical film of claim 1 , wherein the barrier members are filled in and enclosing the opposite groove.
3. The liquid crystal display of claim 1 ,wherein the barrier members are plastic material.
4. A liquid crystal display, comprising: a display board; a first optical film; and a second optical film arranged between the first optical film and the display board; wherein the first optical film comprises: an outer surface; a plurality of protrusions protruding from the outer surface and extending substantially parallel to a first axis; a plurality of grooves formed between neighboring protrusions; and two barrier members arranged at opposite sides of the optical film substantially parallel to a second axis, which is substantially perpendicular to the first axis and preventing each slot from communicating with the exterior, wherein the barrier members are integrally formed with the optical film.
5. The liquid crystal display of claim 4 , wherein the barrier members are filled in and enclosing the opposite ends of each groove.
6. The liquid crystal display of claim 4 , wherein the barrier members are plastic material.
