Abstract
The present invention relates to an apparatus and method for repairing a liquid crystal display panel, which is capable of improving a yield thereof by darkening a bright point to minimize a defect ratio thereof. An apparatus for repairing a liquid crystal display panel according to the present invention includes: a liquid crystal display panel including a repair film formed on any one of a first substrate and a second substrate, which are facing to each other with a liquid crystal layer therebetween; and a laser irradiating device to irradiate a laser to the repair film to darken a specific area of the repair film, which is corresponded to an area where a bright point appears in the liquid crystal display panel.
