  • Publication number: 20180165996
    Abstract: The present invention prevents an advance of a crack in a covering layer, without exposing a support. In a region between an edge part of a moistureproof layer (12) and a display region (2), wavy recessed patterns (7a, 7b, and 7c) are continuously or discontinuously provided so to connect one end of the moistureproof layer (12) and another end of the moistureproof layer (12). Each of the wavy recessed patterns (7a, 7b, and 7c) is recessed and is configured to change a direction in which a crack having appeared in the edge part of the moistureproof layer (12) advances.
