Abstract
An optical display includes an optical display element including a second substrate, a first substrate facing the second substrate, a dummy region and a metal interconnection layer thereon. A first polarizing plate on an upper surface of the optical display element has a light shielding layer therein including printed patterns separated from each other. A first printed layer includes a first point at an interface between the display and non-display regions and a second point at a vertex closest to the first point. A second printed layer includes a third point at the interface and a fourth point at a vertex closes to the third point. The light shielding layer satisfies H≤P/2, where H is a minimum value among a distance from the interface to the second point and a distance from the interface to the fourth point, and P is a width of the dummy region.
