Abstract

The present invention relates to a touch panel which senses contact or the approach of a touch means including human fingers, and which generates a coordinate signal corresponding to the relevant point of touch. The touch panel comprises: substrate (30) made of light-transmitting materials; plurality of first signal lines (32) and second signal lines (34) arranged on one surface of substrate (30) to input and output point detection signals; touch cell (60) arranged in each of the sections formed by dividing an active region on substrate (30), in which a touch occurs, and which includes three-terminal switching element (40) interposed between first signal line (32) and second signal line (34) in each of the sections, and conductive pad (50) connected to the gate terminal of switching element (40); and touch point detection unit (70) which applies point detection signals to first signal lines (32), and receives the point detection signals at second signal lines (34) in accordance with the change in the state of switching element (40) when a touch means is brought into contact with or approaches conductive pad (50) to acquire coordinate signals of the relevant touch cell (60). The touch panel of the present invention senses light contact or the approach of a touch means without causing a curvature of substrate (30) to generate touch signals, and enables the recognition of multiple touch points. The touch panel of the present invention has a single substrate to prevent degradation of transmittivity. The touch panel of the present invention is lightweight, thin, and small, and can thus be installed within a display device.
