<P>PROBLEM TO BE SOLVED: To provide a light guide plate enhancing the luminance of a specific region of the light guide plate by the arrangement of dots. <P>SOLUTION: The light guide plate is provided with an upper surface and at least one side direction plane of incidence, and has a lamp combined to correspond to at least one side direction plane of incidence. A plurality of first dots are provided on the upper surface of the light guide plate, and a plurality of second dots distributed between the clearances of the first dots are separately provided within at least one specific region. The reflectance in the specific region is thereby enhanced, and the uniformity of luminance of the light guide plate is increased. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
