The invention provides a glass cover plate, a production method thereof and a mobile terminal. The production method comprises the following steps of: carrying out cutting and hot pressing a glass substrate, so as to obtain a double-curved surface glass substrate, wherein the edges of the front and rear surfaces of the double-curved surface glass substrate are arc-shaped surfaces, and the bending directions of the arc-shaped surfaces at the edges of the front and rear surfaces of the double-curved surface glass substrate are the same; and carrying out spraying, prebaking, exposure and development for at least two times on the rear surface of the double-curved surface glass substrate so as to obtain a first region covered with at least two first preset color layers, namely a double-curved surface glass cover plate, wherein the first region is the region, except a preset middle view window region and preset openings, on the double-curved surface glass substrate. According to the technical scheme, the 3D double-curved surface glass cover plate with specific colors is formed and has a novel and attractive appearance, so that the requirement of people on the high-grade appearance of the glass cover plate is met, and the problems that existing glass cover plate are planer or 2.5D, are seriously homogenized and are difficult to meet the requirement of people on the high-grade appearance are solved.
