Abstract: PURPOSE:To obviate generation of unequal display and to obtain a high quality and high reliability display by successively laminating a light reflection material and a heat insulating material on the outer peripheral surface of a long-sized light source disposed at the end face of a light transmission plate to coat this outer peripheral surface. CONSTITUTION:The one main surface of the light transmission plate 11 is provided with a light reflection means 12 and the other main surface is provided with a light diffusion plate 13 made of a PET or polycarbonate. The long-sized cylindrical light source 14 is disposed along the end face of the light transmission plate 11. The outer periphery of the light source 14 is provided with the light reflection material 15 formed by depositing silver by evaporation on a PET sheet. Further, the outer peripheral surface side of the light reflection material 15 is covered with the heat insulating material 16. In such a case, the light source 14 heats the light reflection material 15 very close to the light source but the light reflection material is covered with the heat insulating material 16 and, therefore, the heated up light reflection material 15 has an effect of immediately heighten the temp. of a liquid crystal panel 9 and the temp. rise of the liquid crystal near the light reflection material 15 decreases. The unequal temp. is thus lessened and the unequal display is obviated.

IPC: H02G1/12
Filed: 1994-03-31
Abstract: PURPOSE:To provide a small and inexpensive stripping mechanism which can deal with other type of wire harness with high workability. CONSTITUTION:A pair of cutter carriers R1, R2 are disposed on the opposite sides of a wire feed path PH. The cutter carriers R1, R2 carry a plurality of types of stripping cutters 20 integrally.
