Abstract
An active device substrate includes an active device and an electrode. The electrode includes a first light shielding conductive pattern, a second light shielding conductive pattern, a third light shielding conductive pattern, and a first metal oxide protection pattern. The first light shielding conductive pattern, the second light shielding conductive pattern, and the third light shielding conductive pattern are sequentially stacked to form a conductive stack. The conductive stack is disposed in an opening of the first metal oxide protection pattern. A first portion, a second portion, and a third portion of the first metal oxide protection pattern respectively contact a sidewall of the first light shielding conductive pattern, a sidewall of the second light shielding conductive pattern, and a sidewall of the third light shielding conductive pattern. Materials of the first portion, the second portion, and the third portion of the first metal oxide protection pattern are the same.
