Title:
CONDUCTIVE POLARIZING-COLOR FILTER AND DISPLAY DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/010672
Kind Code:
A1
Abstract:
The present invention relates to a conductive polarizing-color filter capable of simplifying the structure of a display device and remarkably reducing the thickness thereof, the filter comprising: a plurality of first electrodes which are made of a conductive material and which are arranged in a first direction with a set width and a set pitch; an insulation layer for covering the first electrodes; and second electrodes which are made of a conductive material, which are arranged on the insulation layer in the first direction, and which overlap with the first electrodes so as to form a waveguide that causes resonance with the first electrodes, wherein the first electrodes and the second electrodes reflect light, from incident light, that is parallel with the first electrodes and the second electrodes and transmit a light vertical thereto, and adjust an overlap area of the first electrodes and the second electrodes so as to cause the transmitted light to resonate at a set wavelength.
