Filed: 2002-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To prevent emission lines from becoming prominent by reducing the brightness of the emission lines appearing at each prism near an incident surface even if a point light source is used.  <P>SOLUTION: Since first and second prisms 28 and 30 are linearly symmetrical with a straight light vertical to an incident surface 16 as a reference, brightness in the left and right sections of a light-guiding plate 14 can be made uniform. Since the first, second, and third prisms 28, 30 and 32 are arranged within a range of directivity of a light source 18 in the incident surface 16, light from the light source 18 can directly enter a section on the incident surface 16 where the third prisms 28 and the like are arranged, thus diffusing light in a wide range of the light-guiding plate 14. Additionally, since the light can be dispersed to the prisms 28 and the like, light gathering at the groove bottom of each prisms 28 and the like can be made smaller than a case where two prisms are formed, thus reducing the brightness of the emission lines appearing at each prism 28 and the like.  <P>COPYRIGHT: (C)2004,JPO
