The present invention relates to a polyamide-imide resin for an optical member having both high flexibility and bending resistance, in particular, a polyamide-imide resin for a front plate of an image display device, and a front plate including the polyamide-imide resin. An object is to provide an optical member. Equations (1) and (2): [In Formula (1) and Formula (2), X and Z each independently represent a divalent organic group, Y represents a tetravalent organic group, and a polyamideimide resin having a structural unit represented by .
