    Abstract: A keypad assembly includes a light guide plate adapted to transmit light and comprising a supporting portion and an elastic portion made of different material than material of the supporting portion, at least one key button disposed on the side of the light guide plate where a first surface of the light guide plate is located, and at least one reflection pattern locally formed on the light guide plate and adapted to reflect light transmitted into the light guide plate toward the key button. The elastic portion is disposed below the key button.
