摘要： A keypad assembly for radiating light to a key button using a light conductive plate is provided. The keypad assembly having a key pad with key buttons includes: a light conductive plate for advancing light emitted through a side surface thereof into the inside thereof and for radiating light to the key buttons by a reflection pattern; a light emitting element for emitting light through the said side surface of the light conductive plate into the inside of the light conductive plate; and a reflecting plate formed in a side surface of the light conductive plate to which light emitted from the light emitting element is directed to reflect light into the inside of the light conductive plate. Therefore, by reflecting light that would otherwise be discharged outside the keypad assembly to the inside of the light conductive plate using the reflecting plate, the light can be used. Accordingly, a light utilization efficiency can be improved, the quantity of light emitting elements can be reduced, and power consumption can be reduced.
