Abstract
There are provided an input sensor having improved input sensing sensitivity, a method for manufacturing the input sensor, and a display device having the input sensor.
Claims20
An input sensor comprising:
- a base part including a sensing region and a peripheral region disposed at the periphery of the sensing region;
- a plurality of sensing electrodes provided in the sensing region;
- an insulating layer provided on the base part and insulating the plurality of sensing electrodes from each other;
- and
- a plurality of signal lines connected to the plurality of sensing electrodes, the plurality of signal lines being arranged to be spaced apart from each other,
- wherein the thickness of the insulating layer corresponding to the sensing region is different from that of the insulating layer corresponding to the peripheral region.

A method for manufacturing an input sensor, the method comprising:
- providing a base part that includes a sensing region and a peripheral region disposed at the periphery of the sensing region;
- providing a first conductive layer on the base part;
- forming a first conductive line by patterning the first conductive layer;
- providing an insulating layer on the base part and the first conductive line;
- forming a contact hole in the insulating layer such that a portion of the first conductive line is exposed;
- providing a second conductive layer on the insulating layer to be in contact with the first conductive line through the contact hole;
- and
- forming a second conductive line by patterning the second conductive layer,
- wherein the thickness of the insulating layer corresponding to the peripheral region is formed thicker than that of the insulating layer corresponding to the sensing region.
