Abstract
A method of manufacturing a touch screen substrate includes forming a sensing electrode on a substrate, spraying a first ink and a second ink having a same amount of ink as the first ink to respectively form a first ink droplet and a second ink droplet on a light blocking region of the substrate, and irradiating a first light upon the first ink droplet to form a first spacer having a first height and a second light upon the second ink droplet to form a second spacer having a second height lower than the first height. A total energy of the first light irradiated upon the first ink droplet differs from a total energy of the second light irradiated upon the second ink droplet, and the second spacer makes contact with the sensing electrode.
