Abstract
The present invention makes it possible to recognize proximity of a coil without an increase in material cost and production cost. A liquid crystal display panel includes a TFT substrate (6) and a CF substrate (7). A touch panel (2) includes (i) a plurality of touch sensing electrodes (3) which are provided on the TFT substrate (6) so as to detect an electric capacitance between the touch panel (2) and a subject of a touch or a change in the electric capacitance and (ii) a proximity sensing electrode (4) which is provided on the CF substrate (7) so as to detect proximity of a coil (10).
Claims9
A display with a built-in touch panel comprising:
- a touch panel;
- and
- a display with the touch panel,
- said display including (i) a circuit substrate, (ii) a counter substrate which is provided so as to face the circuit substrate, and (iii) a liquid crystal layer which is provided between the circuit substrate and the counter substrate,
- said touch panel including a plurality of touch sensing electrodes and a proximity sensing electrode,
- the plurality of touch sensing electrodes being provided on at least one of the circuit substrate and the counter substrate so as to detect an electric capacitance between the touch panel and a subject of a touch or a change in the electric capacitance,
- the proximity sensing electrode being provided on at least one of the circuit substrate and the counter substrate so as to detect proximity of a coil.
