  • Patent number: 10712619
    Abstract: At a corner of a TFT substrate where sealants are coated overlapping each other, a phenomenon that the sealants protrude into the display region is prevented by a structure that: the TFT substrate having an organic passivation film is formed as far as the outside of the display region. A groove-like organic passivation film removed portion is formed surrounding the display region. Since the sealants are coated overlapping each other at the corner, when a TFT substrate and a counter substrate are superposed at a predetermined gap, the width of the groove-like organic passivation film removed portion is made larger at the corner than the side in order to prevent the sealant from extending. Since an excessive sealant is absorbed in the groove-like organic passivation film removing portion of a larger width at the corner, the sealant can be prevented from protruding to the inside of the display region.
