Problems solved by technology

However, since the optical type pressure sensor requires an additional waveguide, there is a problem in that the thickness of the touch panel increases
However, since the thickness of the touch panel 100 cannot be increased as the thickness of the insulating layer 130 increases, there is a problem that the thickness of the display device including the touch panel 100 also increases.

Abstract

Provided is a touch panel. The touch panel includes a first substrate, a second substrate, a first electrode, a second electrode, a third electrode, and a dielectric layer. The second substrate faces the first substrate. The first electrode is on one surface of the first substrate. The second electrode is spaced apart from the first electrode on a same plane as the first electrode. The third electrode is on one surface of the second substrate and overlaps the first electrode and the second electrode. The dielectric layer is between the first electrode and the third electrode and between the second electrode and the third electrode and includes an anisotropic dielectric material.

Description

technical field [0001] The present disclosure relates to a touch panel and a display device including the touch panel. More particularly, the present disclosure relates to a touch panel capable of sensing 2D coordinates and touch input force of a touch input and a display device including the touch panel. Background technique [0002] A touch panel as a device for sensing a user's touch input such as screen touch or gesture on a display device has been widely used in applications such as public facilities in addition to being applied to portable display devices including smart phones, tablet PCs, etc. display devices and large display devices such as smart TVs. The touch panel may be classified into a resistive type, a capacitive type, an optical type, an electromagnetic (EM) type, and the like. [0003] Among various touch panels, capacitive touch panels are generally used. In the capacitive touch panel, when the capacitance of touch electrodes intersecting each other is...
