Problems solved by technology

[0005] When the adhesion between such a patterned retardation film and the polarizing plate or polarizer decreases, deformation may occur during handling during manufacturing or use
Also, there may be concerns about peeling or swelling when exposed to heat and humidity for extended periods of time
In addition, typical PVA polarizers can shrink in the pulling direction, thus involving different retarda...

Abstract

The present invention relates to an adhesive composition and a composite polarizing plate using same, more specifically to an adhesive composition and a composite polarizing plate using same, in which the adhesive composition comprises: a photopolymerizable compound containing acrylic monomers having a hydroxyl or carboxyl group, and 6-18 carbon aromatic rings; and a photopolymerization initiator, thereby markedly improving the adhesiveness between a polarizer and a patterned retardation layer when utilized in producing a composite polarizing plate by adhering the polarizer and patterned retardation layer, and contributing to improving heat resistance and moist heat resistance, as well as to imparting a superb three-dimensional effect.

Description

technical field [0001] The present invention relates to an adhesive composition and a composite polarizing plate using the same. Background technique [0002] In general, a display device for obtaining a stereoscopic image, such as a liquid crystal display device, often includes a patterned retardation film. This patterned retardation film has a technical configuration in which the optical axes of the separated pattern regions are formed in directions different from each other to transmit the separated images to the left and right eyes of the viewer wearing polarized glasses, thereby embodying three-dimensionality (ie, stereoscopic) images. [0003] The patterned retardation film is generally prepared by forming an alignment layer on a glass substrate and applying liquid crystal to the alignment film to obtain alignment properties. A photosensitive liquid crystal material is aligned on the alignment layer and then crosslinked by light radiation, such as ultraviolet light, ...
