A display apparatus according to an embodiment of the present invention includes: a display element; and a circularly polarizing plate placed on a viewer side of the display element. The circularly polarizing plate includes a polarizer and a retardation film. In-plane retardations of the retardation film satisfy a relationship represented by the below-indicated expression (1); and an angle θ1 formed between a slow axis of the retardation film and a direction in which a wiring crimping portion provided along at least one side of a peripheral edge portion of the display element extends satisfies a relationship represented by the below-indicated expression (2):Re(450)<Re(550)  (1)θ1≦70°  (2)where Re(450) and Re(550) represent in-plane retardations measured at 23° C., and at wavelengths of 450 nm and 550 nm, respectively."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device and method for manufacturing same","description":"There is provided a display apparatus that can suppress the occurrence of a crack in a circularly polarizing plate in its manufacturing process without reducing designability and mass productivity.
