An electronic device is disclosed. The electronic device of the present disclosure includes a light emitting unit for providing image light, and a display unit for reflecting the image light and transmitting the reflected image light to eyes of a user. The display unit includes a lens unit and a reflective surface for reflecting the image light. The reflective surface is formed of a 3-dimensional curved surface having different curvatures in a first direction and in a second direction perpendicular to the first direction, thereby correcting astigmatism. An electronic device according to the present invention may be associated with an artificial intelligence module, robot, augmented reality (AR) device, virtual reality (VR) device, and device related to 5G services.
