Abstract PURPOSE: A convertible key pad package is provided to improve a pattern display quality by preventing patterns from being overlapped except corresponding patterns. CONSTITUTION: A convertible key pad package includes a plurality of waveguide sheets(10A,10B), and a plurality of light shielding sheets(20A,20B). The pattern is formed on one side of the waveguide sheet. A light shielding sheet is laminated on the waveguide sheet. The light shielding sheet includes a light transmitting unit, a transparent layer, and a printing layer. The shape of the light transmitting unit corresponds to the pattern of the waveguide sheet. The printing layer is formed on the surface of the transparent layer. The printing layer shields the light inputted to the area except the light transmitting unit.
