A display panel and a mobile device with the display panel are provided. The display panel includes a display module and a back light unit. The display module includes a glass substrate for displaying videos by controlling a transmittance and a color of light, an upper polarizer that is placed on an upper side of the glass substrate, and a lower polarizer that is placed on a lower side of the glass substrate and exposes an edge of the glass substrate. The back light unit includes: a light source, a light waveguide that is placed on a lower side of the lower polarizer and that transfers light from the light source to the lower polarizer, and a Flexible Printed Circuit Board (FPCB), which is placed at the edge of the glass substrate exposed by the lower polarizer, that supplies electric power to the light source, and that reflects light from the light source to the light waveguide. The display panel is cost-effective and has high optical efficiency.
