Problems solved by technology

When the polarizing plate is removed in the reprocessing process, the substrate is greatly deformed because the stress is added to the substrate through the adhesive layer formed on the entire surface of the polarizing plate
Then, plastic deformation or movement of the spacer material supporting the cell gap occurs, and gap non-uniformity occurs

Embodiment Construction

[0024] Examples of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] [first example]

[0026] An LCD panel as an optical display device according to a first example of the present invention has a TFT substrate, a counter substrate, a liquid crystal material interposed between the TFT substrate and the counter substrate, a liquid crystal material that seals between the TFT substrate and the counter substrate A sealing material, a polarizing plate arranged so that the surfaces of the TFT substrate and the opposite substrate can be covered, and an adhesive layer for fixing the polarizing plate on the TFT substrate and the opposite substrate, respectively. The adhesive layer is formed only on the peripheral portion of the LCD panel without being formed on the portion of the display area including the polarizing plate.

[0027] By adopting the above-described structure, the bonding strength between the polarizing plate and ...

Abstract

An optical display device of the invention includes an optical display panel, an optical film arranged so that at least one side of a surface on the optical display panel can be covered, and an adhesive layer for fixing the optical film on the optical display panel, wherein the adhesive layer is arranged outside a transparent substrate constituting the optical display panel as seen from a normal direction to a display surface of the optical display panel, and there is no gas layer between said optical film and the display area on the optical display panel.

Description

[0001] incorporated by reference [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2008-033691 filed on February 14, 2008, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to an optical display device and a manufacturing process thereof, and in particular, to a liquid crystal display (LCD) device and a manufacturing process thereof. Background technique [0004] An LCD panel, which is a representative of an optical display device, is generally provided with a TFT substrate, a counter substrate, a liquid crystal material interposed between the TFT substrate and the counter substrate, a sealing material for sealing the liquid crystal material between the pair of substrates, and a polarizer. A polarizing plate arranged so that the surfaces of the TFT substrate and the counter substrate can be covered. [0005] Each of the polarizing pl...
