    Abstract: A first recess part is defined on an organic layer disposed in a non-display area, and a frame sealant is filled in the first recess part. A depth of the first recess part is less than a thickness of the organic layer. Therefore, a relative contact area between the frame sealant and a first substrate is increased. As such, strength of adhesion between the frame sealant and the substrate is further increased, and a capability of panels to pass peeling tests is improved.
