1. A liquid crystal display (LCD) having a built-in touch screen panel, the LCD comprising:
- a lower substrate having a pixel electrode formed on an upper surface of the lower substrate;
an upper substrate having a black matrix, sensing patterns, color filters, a common electrode, and metal electrodes formed on a bottom surface of the upper substrate, wherein the metal electrodes are disposed to overlap the black matrix formed along an edge of the bottom surface of the upper substrate and are coupled to the sensing patterns; and
a liquid crystal layer interposed between the lower substrate and the upper substrate.

Abstract
There is provided a liquid crystal display (LCD) with a built-in touch screen panel in which the touch screen panel is built-in the LCD. The LCD with the built-in touch screen panel includes a lower substrate on whose upper surface a pixel electrode is formed, an upper substrate on whose bottom surface facing the lower substrate sensing patterns, color filters, and a common electrode are sequentially formed, and a liquid crystal layer interposed between the lower substrate and the upper substrate.
