摘要： A backlight device is provided to apply a thin-film transparent resin having predetermined hardness as well as flexibility and light transmission properties to a light guide plate having a light guide pattern unit, thereby obtaining brightness required as a minimum light source. A light guide plate(10) is equipped with a light guide pattern unit on a lower side to diffuse and scatter light in uniform illumination. An LED(Light Emitting Diode) unit(20) is installed in at least more than one on a sidewall of the light guide plate(10), and irradiates light to the light guide plate(10). A keypad(30) is equipped with a key assembly(35) on one side as having a resin layer(32), a base resin layer(34), and a character-shaped character opening unit(31), and is located on an upper side of the base resin layer(34). A PCB(Printed Circuit Board)(22) includes a metal dome switch(24) located on a lower side of the light guide plate(10).
