An organic-inorganic hybrid resin is formed by reacting a polyol organic resin with a polysilsesquioxane polymer. The organic-inorganic hybrid resin has T0, T1, T2, and T3 signals of 29Si-NMR, wherein a ratio of the sum of 3 times the integral value of T0 signal and 2 times the integral value of T1 signal and the integral value of T2 signal and the integral value of T3 signal ((3T0+2T1+T2)/T3) is from 0.3 to 1.2, wherein the T0 signal range is 35 ppm to 40 ppm, the T1 signal range is 48 ppm to 53 ppm, the T2 signal range is 55 ppm to 62 ppm, and the T3 signal range is 63 ppm to 72 ppm.
