Liquid Crystal Display Device
First Claim
1. A liquid crystal display device comprising:
- a liquid crystal display panel including a liquid a TFT substrate and a color filter substrate with a crystal layer put between the substrates; and
a touch panel;
wherein the TFT substrate has a terminal portion formed thereon, the terminal portion being located where the TFT substrate does not overlap with the color filter substrate;
the TFT substrate is bonded with a lower polarizing plate at the lower side of the TFT substrate;
the touch panel is constructed from a single substrate;
the touch panel is bonded directly to the color filter substrate by way of an adhesion layer;
the touch panel is bonded with an upper polarizing plate; and
the upper polarizing plate is bonded with a front window by way of an adhesion layer, the front window covering the terminal portion of the TFT substrate.

Abstract
A liquid crystal display device includes a touch panel constructed from a single substrate plate and disposed over a liquid crystal display panel. A color filter is disposed over a TFT substrate, and the touch panel is bonded onto the color filter substrate by way of a first adhesion layer. An upper polarizing plate is bonded over the touch panel, and a front window is bonded over the upper polarizing plate via a second adhesion layer. The front window covers a terminal portion which is a portion where only the TFT substrate exists so as to physically protect the portion. Since the upper polarizing plate is disposed over the touch panel, the connection portion of the flexible wiring substrate for the touch panel does not contact with the front window. Thus, the touch panel can be prevented from being strained.
