Abstract

The present invention provides a detergent composition for removing liquid crystal and a cleaning method of a liquid crystal panel, wherein the detergent composition has high cleaning power to liquid crystal and can reduce the water discharging load to environment. The detergent composition for removing the liquid crystal is characterized by comprising an aromatic compound which is represented bya general formula (1) [in the formula, R<1> represents OCH3 or CH2OCH3, R<2> represents CH3, OCH3 or CH2OCH3]. The cleaning method of the liquid crystal panel is characterized by using the detergent composition for removing liquid crystal. The detergent composition for removing liquid crystal is preferably formed by mixing the aromatic compound represented by the general formula (1) and water.

Description

technical field [0001] The present invention relates to a liquid crystal removal cleaning composition and a liquid crystal panel cleaning method. This application claims priority based on Japanese Patent Application No. 2008-229785 filed in Japan on September 8, 2008 and Japanese Patent Application No. 2009-125163 filed in Japan on May 25, 2009, the contents of which are incorporated herein. Background technique [0002] Usually, a pair of glass substrates formed with electrodes and an alignment film are bonded together with an adhesive to leave a part of the opening to make a liquid crystal chamber, inject liquid crystal into the liquid crystal chamber, seal the opening with a sealant, and then clean it. A liquid crystal panel was manufactured by adhering a deflection plate to the surfaces of the pair of glass substrates. [0003] In such production, it is unavoidable that a void portion (narrow portion) is generated outside the bonded portion between the pair of glass sub...
