Embodiment approach 1

[0096] Sensing electrodes including conductive polymers are disposed on the substrate. The touch window is manufactured by disposing a cover substrate on a resin layer.

[0097] The chromaticity index (b*) of the sensing electrode has a negative value, and the chromaticity index of the resin layer has a value of about 3.

[0098] Then, the chromaticity index of the stacked structure in which the sensing electrode and the resin layer were stacked was measured.

Embodiment approach 2

[0100] The same touch window as Embodiment Mode 1 was manufactured except that the resin layer had a chromaticity index (b*) value of about 7, and the chromaticity index of the stacked structure of the sensing electrode and the resin layer was measured.

Embodiment approach 3

[0102] The same touch window as Embodiment Mode 1 was manufactured except that the resin layer had a chromaticity index (b*) value of about 12, and the chromaticity index of the stacked structure of the sensing electrode and the resin layer was measured.

Abstract

A touch window according to one embodiment includes a substrate and an electrode structure on the substrate. The electrode structure includes an electrode layer on the substrate; and a resin layer on the electrode layer. The electrode layer include: a sensing electrode and a wire electrode, and the electrode structure has a chromatic index (b*) of 0 (zero) or more.

Description

technical field [0001] This embodiment relates to a touch window. Background technique [0002] Recently, a touch window that performs an input function by touching an image displayed on a display device by an input device such as a stylus pen or a finger has been applied to various electronic devices. [0003] Touch windows can generally be classified into resistive touch windows and capacitive touch windows. In a resistive touch window, the touch point is detected by shorting the glass to the electrodes due to the pressure of the input device. In the capacitive touch window, when a user's finger touches the capacitive touch window, the position of the touch point is detected by detecting a change in capacitance between electrodes. [0004] In resistive touch panels, its repeated use degrades its performance and causes scratches. Therefore, interest in capacitive touch panels exhibiting excellent durability and having a long lifespan has increased. [0005] A touch wind...
