<p>The present invention relates to a liquid crystal protection sheet which protects a touchscreen panel of a display terminal. The liquid crystal protection sheet includes: a sapphire sheet processed to a display panel size; an ultra-thin antifouling coating layer formed on a top surface of the sapphire sheet; a lower adhesion layer formed on a bottom surface of a shatterproof film by coating low adhesion silicone; and a high adhesion layer formed on a top surface of the shatterproof film by coating high adhesion acrylic or high adhesion silicone. The liquid crystal protection sheet is manufactured by laminating the high adhesion layer on a bottom surface of the sapphire sheet having the antifouling coating layer. By using single sapphire crystals that are the next hardest substance from which diamonds are formed in place of tempered glass, a liquid crystal protection sheet with surface hardness, compressive strength and robustness better than the tempered glass may be provided. The liquid crystal protection sheet is better than the tempered glass in strength to provide the liquid crystal protection sheet having a thinner thickness, thereby guaranteeing fine touch sensitivity. Since the strength of the liquid crystal protection sheet is excellent, the liquid crystal protection sheet that is less liable to be damaged in manufacturing processes or distribution and in use may be provided.</p> |
