Abstract
The present invention relates to a substrate for a display device and, more particularly, to a substrate for a display device which has excellent durability and also can minimize generation of color shift when being applied to a display device. To this end, the present invention provides a substrate for a display device comprising: a base material; a first coating film formed on the base material; a second coating film which is formed on the first coating film and is formed of a material having a relatively lower refractive index than the first coating film; a third coating film which is formed on the second coating film and is formed of a material having a relatively higher refractive index than the second coating film; a forth coating film which is formed on the third coating film and is formed of a material having a relatively lower refractive index than the third coating film; and a hard coating film which is formed on the fourth coating film and is formed of AlON having a relatively higher refractive index than the forth coating film.
