A touch sensor apparatus is provided to minimize power consumption by forming the rear surface lighting of the uniform luminance with a small number of light-emitting diodes. A touch sensor apparatus includes a light guide plate(230), an electrode layer(240), and at least one optical source(221,222). The light guide plate(230) guides light which is a backlight. The electrode layer(240) is located on an upper part or a lower part of the light guide plate(230). At least one electrode pattern is formed on one surface of the electrode layer(240) in contact with the light guide plate(230). The optical sources(221,222) are located on side surfaces of the light guide plate(230) and the electrode layer(240). The optical source(221,222) generates the light to be guided to the light guide plate(230). |
