<P>PROBLEM TO BE SOLVED: To provide a refraction-condensing plate for a backlight which can obtain full condensing effect, by aligning two-dimensional synchrotron emitted from a light source in parallel with the lateral width direction and the vertical direction, and which can acquire full condensing effect. <P>SOLUTION: The refraction condensing plate for the backlight is made, by combining a first lens 1 which controls an incident light in the vertical direction and a second lens 2 which controls the incident light in the lateral width direction. Moreover, the refraction condensing plate for the backlight is a refraction condensing plate for aligning the central axis of the thickness direction of itself in the direction of the two-dimensional synchrotron radiation emitted from the light source. It is preferable that the first lens 1 which make the incident light converge to the first central axis surface which passes along the central axis, and a second lens 2 which makes the incident light converge to the second central axis surface (different from the first central axis surface) which passes the central axis is located in the incident light side and the exiting light side, respectively. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
