First Claim
Patent Images
1. A flat display device with touch panel, comprising:
- a flat display device including;
a plane light source; and
a display panel with a lower substrate and an upper transparent substrate; and
a touch panel on said upper transparent substrate, including;
a first transparent electrode layer on said upper transparent substrate;
a second transparent electrode layer on said first transparent electrode layer;
a transparent plate on said second transparent electrode layer; and
a polarizer on said transparent plate.

Abstract
The upper polarizer of a flat display device is located on the upper transparent electrode of the touch panel that is combined with the flat display device. Therefore, the flat display device and the touch panel can share a glass or plastic substrate and a flexible printed circuit board substrate on the second electrode layer.
