The present invention relates to a transparent plastic sheet, of which transmittance of the whole sheet is 89-94% as measured based on ASTM D1003. More particularly, the transparent plastic sheet comprises: a first layer including a polycarbonate (PC) layer; a second layer stacked on an upper surface of the first layer, and composed of a methylmethacrylate-styrene (MS) layer; and a third layer stacked on an upper part of the second layer, and composed of a polymethyl methacrylate (PMMA) layer. According to the present invention, the transparent plastic sheet has minimized alteration under the conditions of high temperature, thereby being useful for various display products as a window cover replacing glasses. |
