PURPOSE:To prevent the threshold voltage of a liquid crystal from changing with the lapse of time due to the heat generated by a back light installed on the back side of a liquid crystal panel. CONSTITUTION:A light 6 is installed in the side of a light guiding plate 5 and a reflecting means 9 to effectively utilize the light of the light 6 is installed and they are united. Since the reflecting means is made of a metal, holes 12 are formed in the lower side frame 11 which corresponds to a high heat part to release the heat which affects the liquid crystal through them. |
