PURPOSE: A light guide plate is provided to reduce the size and the thickness of a light guide plate, and combine a function of a prism sheet, thereby reducing parts of a back light unit and simplifying assembling. CONSTITUTION: A PMMA(Polymethylmeth acrylate) resin is pressed out to manufacture lenses formed in certain shape in a length direction. If light enters a light guide plate, the light does not proceed in right and left directions due to focusing of the lenses formed under the PMMA resin and the light becomes focused after being reflected. Loss of brightness and light through side surface parts is prevented and the light repeatedly goes straight ahead to be prevented from diffusing. |
