Claims

[Claims for Utility Model Registration] A device for detecting the position of a defect in an attached liquid crystal panel by lighting up the liquid crystal panel, comprising: a defect position indicating member that is moved to the defect position; and the defect position indicating member. a wire means connected to the wire means whose payout length changes as the defect position indicating member moves; a length measuring means that measures the payout length of the wire means; and a wire means which measures the payout length of the wire means, based on the payout length measured by the length measuring means. A liquid crystal panel defect position detection device comprising a defect position calculation means for calculating the position of the defect position indicating member.
