Abstract: PROBLEM TO BE SOLVED: To prevent a contaminant which exudes from a capping material or a sealing material in the vicinity of an injection port from penetrating into a pixel area and to suppress picture quality defects liable to occur at an injection port part in a liquid crystal display device. SOLUTION: The contaminant which exudes from the capping material 16 is prevented from penetrating into a display area 13 and defective picture quality liable to occur in the display area 13 is suppressed by forming an injecting port pole structure 18 compatible with a liquid crystal in a region in the vicinity of the injection port 15 of the liquid crystal. That is, the liquid crystal display device having an array substrate 11 and a CF substrate which are deposed while keeping a prescribed interval between them and the liquid crystal sealed in a gap between them is provided with a pole structure 17 for controlling the gap, the sealing material 14 provided outside the display area 13 for sealing the liquid crystal in the gap and forming the injection port 15 which is opened for injecting the liquid crystal, the capping material 16 for capping the injection port 15 after the liquid crystal is sealed and the injection port pole structure 18 formed in the region in the vicinity of the injection port 15 and dividing the injection port 15 into plural parts using the same material as the material of the pole structure 17.
