Abstract
In a liquid crystal display (LCD) unit for a cellular phone or the like, the conventional reflection tape attached to the lightguide is eliminated in favor of a reflection strip disposed on a reflection area of the printed circuit board (PCB). The reflection strip serves to reflect light from the PCB back to the LCD display area and/or the keys of the keypad. By eliminating the reflection tape, manufacturing is made easier and manufacturing costs are reduced.
