Abstract
The present invention relates to a substrate for a display device and, more particularly, to a substrate for a display device, which not only has excellent durability, but can also minimize the occurrence of color shift when applied to a display device. To this end, the present invention provides a substrate for a display device, which is characterized by including: a substrate; a hard coat film formed on the substrate and formed of AlON; and a multilayer film formed between the substrate and the hard coat film, and formed of a coating film having a first refractive index and a coating film having a second refractive index, which are repetitively stacked in sequence.
