According to an embodiment of the present invention, a smartphone includes: a cover layer; an LCD panel which is located on the lower part of the cover layer, includes a first glass layer and a second glass layer located to have the liquid crystal layer interposed therebetween, and allows at least a portion of a touch sensor, which senses touch in a capacitive method, to be located between the first glass layer and the second glass layer; and a backlight unit which is located on the lower part of the LCD panel and includes an optical film, a light source, a reflection sheet, and a cover. The backlight unit additionally includes a pressure sensor which is located between the reflection sheet and the cover and is attached on the cover. The touch sensor includes a plurality of driving electrodes and reception electrodes. A driving signal is applied to the touch sensor, and a touch location can be detected from a sensing signal output by the touch sensor. A level of touch pressure can be measured based on a change amount of capacitance outputted from the pressure sensor. |
