Abstract:
A sensor for measuring living body information and a keypad assembly including the sensor includes a light guide panel for guiding a first light. A light extracting pattern is provided on the light guide panel for outputting the first light guided by the light guide panel to an exterior of the light guide panel. A light coupling pattern is provided on the light guide panel for changing a proceeding direction of a second light incident from the exterior of the light guide panel, so that the second light is guided by the light guide panel.
