Filed: 2002-06-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a back light unit which permits the thickness reduction of a light transmission plate and can reduce the degradation in the efficiency of utilizing the emission of incident light as far as possible.  <P>SOLUTION: The thickness of a light emitting section 1B arranged on the back of a liquid crystal display element 7 of the light transmission plate 1 is reduced. More specifically, the thickness of the light emitting section 1B is made half the thickness (t) of a light inlet section 1A where a light source 2 is arranged. The cross-sectional shape of the light inlet section 1A is formed into a perpendicular trapezoidal shape having a slope 13 of a gradient θ satisfying 5.7°≤θ≤17.6°. As a result, even if the light emitting section 1B is made thinner than the light inlet section 1A, the incident light from the light source 2 can be efficiently guided to an object for illumination. Accordingly, a thin back light unit 6 which reduces the degradation in the efficiency of utilizing the light can be provided.  <P>COPYRIGHT: (C)2004,JPO
