Abstract: A mobile terminal including a glass panel having a first and a second touch region. The second touch region is, at least in part, located within the first touch region and configured to obtain fingerprint information. The mobile terminal further includes a first and a second touch sensor respectively corresponding to the first and second touch regions, a light guide plate provided at a backside of the first and second touch sensors, and a light source provided on at least one side of the light guide plate, wherein the light guide plate includes a light guide plate body to propagate light from the light source, and windows such that brightness of the second touch region is substantially the same as brightness of a portion of the first touch region that is outside of the second touch region, the windows having different properties including at least one of size and density.
