Converging reflector and liquid crystal display device |
摘要 |
A converging reflector comprises a linear light source having two end points located with a predetermined spacing therebetween, a first reflection surface having a curvature so as to have a focal point at one of the two end points, and a second reflection surface having another curvature so as to have a focal point at the other of the two end points. Accordingly, a light from the linear light source is incident onto the first and second reflection surfaces. Thus, this reflector can project a light as an ideal plane of projection, resulting in improved projection efficiency.
