Abstract
A display device and a method for driving the same are disclosed. In one aspect, the display device includes a plurality of pixels defined on a substrate and a sensor formed in at least one of the plurality of pixels and adjacently arranged at the same vertical level as that of a thin film transistor formed on the substrate to sense bending of the substrate and pressure that is applied to the substrate.
