Title:
OPTICAL LAMINATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/176989
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical laminate in which cracks do not readily occur in a resin film provided to a touch sensor layer when using a laser to cut the optical laminate into a prescribed shape. An optical laminate comprising a front surface panel, a polarization layer, and a touch sensor layer, the touch sensor layer having a transparent conductive layer and a resin film, and a prescribed range being set for a parameter A which is calculated from the glass transition temperature and the absorption of light at a wavelength of 9.3 μm of the resin film provided to the optical laminate.
