Curved surface display device, method for manufacturing curved surface display device and electronic device thereof

A curved surface display device, a method for manufacturing the curved surface display device, and an electronic device thereof. The curved surface display device (10) may comprise: an upper curved surface light transmitting substrate (2), a lower curved surface light transmitting substrate (4) arranged opposite the upper curved surface light transmitting substrate (2), and a sealant located between the upper curved surface light transmitting substrate (2) and the lower curved surface light transmitting substrate (4), coated along the edges of the upper curved surface light transmitting substrate (2) and the lower curved surface light transmitting substrate (4) and having a specific width distribution; the sealant with the specific width distribution enables the upper curved surface light transmitting substrate (2) and the lower curved surface light transmitting substrate (4) to be adhered together and enables the stresses of the upper curved surface light transmitting substrate (2) and the lower curved surface light transmitting substrate (4) to be reduced, while the stress distributions of the upper curved surface light transmitting substrate (2) and the lower curved surface light transmitting substrate (4) are varied.
