Original Abstract Submitted

A data processing device with low power consumption is provided. The data processing device includes a flexible position input portion for sensing proximity or a touch of an object such as a user's palm and finger. The flexible position input portion overlaps with a display portion and includes a first region, a second region facing the first region, and a third region between the first region and the second region. In the case where part of the first region or the second region is held by a user for a certain period, supply of image signals to the part is selectively stopped. Alternatively, a sensing in the part is selectively stopped.
