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.
