Touch screen substrate and method of manufacturing the same

Abstract

In a touch screen substrate and a method of manufacturing the same, the touch screen substrate includes a base substrate, a light blocking pattern, a first sensing element and a first switching element. The light blocking pattern includes an inorganic layer formed on the base substrate and a light blocking layer formed on the inorganic layer, the light blocking layer transmitting an infrared light and absorbing a visible light. The first sensing element is formed on the light blocking pattern and senses the infrared light. The first switching element is electrically connected to the first sensing element. Thus, an undercut may be prevented from being formed at a lower portion of the light blocking pattern, and an adhesive strength between the light blocking pattern and the base substrate may be enhanced.
