PROBLEM TO BE SOLVED: To provide a back light structure of liquid crystal display device which is thin and is easily handleable. SOLUTION: A conductive pattern for light source is formed on a marginal part which is extendedly disposed on the lower glass substrate 2 of the liquid crystal display device 1, a light source 10 is mounted while being connected to the conducting pattern and a reflecting mirror 11b having an inclined surface is integrally formed on the position just under the light source of a light transmission plate 11 disposed on the lower surface of the liquid crystal display device 1. Light of the light source 10 which is turned on is transmitted by the glass substrate 2, is made incident on the reflecting mirror 11b, therein, is reflected by the reflecting mirror 11b, is guided deep in the recesses of the light transmitting plate 11, is radiated from the upper surface 11c and illuminates a display part of the liquid crystal display device 1. |
