Abstract

According to an aspect, a display device with a touch detection function includes: a touch detection electrode that detects proximity or contact of an object; a drive electrode to which the excitation signal is applied; a first substrate on which the drive elements are provided; a second substrate on which at least one of the touch detection electrode and the drive electrode is provided, the second substrate being bonded to the first substrate to face each other via a sealing member; a conductor that electrically is coupled to at least one of the touch detection electrode and the drive electrode; and a conductor support member that fills a space between the first substrate and the second substrate and on the surface of which the conductor is provided.

Claims (36)

1. A display device with a touch detection function comprising:

a plurality of drive elements that perform a display operation based on a pixel signal and a display drive signal;

a touch detection electrode that detects proximity or contact of an object based on an excitation signal;

a drive electrode to which the excitation signal that fluctuates at least in level at a predetermined cycle is applied;

a first substrate on which the drive elements are provided;

a second substrate on which at least one of the touch detection electrode and the drive electrode is provided, the second substrate being bonded to the first substrate to face each other via a sealing member;

a first electrode that is disposed on the first substrate and extends outward beyond an edge face of the second substrate, and that is electrically connected to at least one of the drive electrode and the touch detection electrode;

a plurality of conductors that electrically connect the first electrode and at least one of the touch detection electrode and the drive electrode;

a conductor support member that is made of an electrically insulating resin and that is provided underneath the conductor so as to fill a space between the first substrate and the second substrate at a position of the edge face of the second substrate and extend in a direction from the sealing member to the first electrode; and

a plurality of non-conductive segments arranged between adjacent conductors,

wherein the plurality of conductors and the plurality of non-conductive segments are adhesive.

2. The display device with a touch detection function according to claim 1 , wherein the conductor support member is a resin layer configured to

cover at least a portion from the edge face to a part of a surface of the first substrate, and

become smaller in size in a direction perpendicular to the surface of the first substrate with the separation thereof from the edge face.

3. The display device with a touch detection function according to claim 1 , wherein the conductor is conductive paste.

4. The display device with a touch detection function according to claim 1 , wherein the conductor support member includes

a portion where the conductor is provided and has hydrophilic property, and

a portion where no conductor is provided and has water-repellent property.

5. An electronic apparatus comprising:

a display device with a touch detection function according to claim 1 .

6. The display device with a touch detection function according to claim 1 , wherein the conductor support member is the sealing member that is provided up to a position of the edge face or up to a position away from the edge face.

7. The display device with a touch detection function according to claim 6 , wherein the edge face is configured to become smaller in size in a direction perpendicular to a surface of the second substrate with extension thereof toward the outside of the second substrate.
