Abstract
A liquid crystal display device includes a driving voltage supply line 115 connected to a transfer pad 116 through a contact hole 116a. The contact hole 116a is corroded under the open air in a prior art liquid crystal display device. According to the present invention, however, the contact hole 116a is provided in an air tight space between a display area 103a and a sealing material 300, e.g., underneath the sealing material 300. With this structure the contact hole 116a is not exposed to the open air so that its resistance to corrosion is significantly improved.
Claims5
A liquid crystal display device comprising:
- a circuit array substrate including a plurality of pixel electrodes in a display area of said array substrate;
- a counter substrate including a counter electrode provided opposite to said pixel electrodes;
- a sealing material provided at a periphery of said display area to bind said array and counter substrates together with a predetermined gap;
- a liquid crystal layer filled in a space defined said array and counter substrates;
- a line formed on said array substrate to supply a counter voltage to said counter electrode;
- a connecting component formed on said array substrate to connect said line to a contact hole defined in said connecting component;
- and
- a transfer component to electrically connect said counter electrode to said connecting component,
- wherein said contact hole is provided between said display area and said sealing material.
