Abstract:
The present invention relates to a liquid crystal display (LCD) panel with a built-in touch screen capable of maintaining touch sensitivity at a certain level regardless of touch circumstances, and an LCD having the LCD panel with a built-in touch screen. According to the present invention, there are provided an LCD panel with a built-in touch screen, comprising a first substrate; a second substrate positioned opposite to first substrate; a liquid crystal layer injected between first and second substrates; a sensing unit including a conductive column spacer and a conductive pad spaced apart from conductive column spacer by a predetermined interval to sense a touch point; and a plurality of pressure particles with certain hardness positioned on an outer surface of first substrate. Further, there is provided an LCD having the LCD panel with a built-in touch screen.
