1. A display device comprising:
- a first substrate;
a display element over the first substrate;
a color filter layer over the display element;
a stress relief layer over the color filter layer;
a sensor layer including a first electrode, a second electrode, a third electrode, an insulating layer, and a wiring over the stress relief layer; and
a second substrate over the sensor layer,wherein a product of a specific gravity and a dielectric constant of the stress relief layer is smaller than that of the second substrate.

Abstract
A reduction in the weight of a display device with a touch sensor is achieved while a decrease in the sensitivity thereof is suppressed. The display device includes, between a pair of substrates, a touch sensor, a color filter, and a display portion provided with a display element. A stress relief layer whose product of the dielectric constant and specific gravity is smaller than that of the substrate provided with the touch sensor is provided, whereby parasitic capacitance between an electrode and a wiring included in the touch sensor and an electrode and a wiring included in the display portion can be reduced.
