A liquid crystal display panel includes an active matrix substrate, a counter substrate, a liquid crystal layer, and a sealant. The counter electrode is opposed to the active matrix substrate. The liquid crystal layer is provided between the active matrix substrate and the counter substrate. The sealant, which surrounds the liquid crystal layer between the active matrix substrate and the counter substrate, joins the active matrix substrate and the counter substrate and seals the liquid crystal layer. A portion of the surface on the liquid crystal layer side of the active matrix substrate which is located at the periphery of the liquid crystal display panel is flat.

Display panel comprising at least one mark formed of a thinnest conductive film and a flattening film including a sealing exposing portion

A liquid crystal panelincludes a pair of substrates, liquid crystaldisposed between the substrates, and alignment filmsprovided on the opposed surfaces of the substrates. After formation of the alignment filmoris completed in a manufacturing process, it is checked by an inspection process whether a pinhole H is formed on the alignment film, and further the position of the pinhole H is detected. Thereafter, an alignment film repair filleris applied to the pinhole H by a repair process, so that the pinhole H is repaired.
