A window of an electronic device includes a shooting region at a position corresponding to a camera lens assembly. The window includes a front surface, a rear surface, and an inclined surface. The front surface includes the shooting region and is formed in a curved shape. An inclined surface is disposed to have a slope corresponding to a curvature of the front surface in at least a portion of the rear surface corresponding to the shooting region. Therefore, deterioration of image capture quality such as distortion by the camera lens assembly and internal reflection is effectively prevented by the inclined surface.
