A light guide plate ( 200 ) includes a block body ( 210 ) and a plurality of first prisms ( 220 ). The block body ( 210 ) has a light input surface ( 211 ), a light output surface ( 212 ) adjoining the light input surface ( 211 ) and a bottom surface ( 213 ) opposite to the light output surface ( 212 ). The light input surface ( 211 ) includes a plurality of flat portions ( 216 ) and at least one inwardly curved portion ( 215 ). The first prisms ( 220 ) are arranged on the inwardly curved portion ( 215 ) of the light input surface ( 211 ) and extend from the bottom surface ( 213 ) of the block body ( 210 ) to the light output surface ( 212 ) of the block body ( 210 ).
