Title:
IN-CELL LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/181479
Kind Code:
A1
Abstract:
The present invention provides an in-cell liquid crystal panel having: an in-cell liquid crystal cell that is provided with a liquid crystal layer, a first transparent substrate and a second transparent substrate sandwiching the liquid crystal layer on both sides, and a touch sensing electrode portion related to touch sensor and touch-driven functions between the first transparent substrate and the second transparent substrate; and a polarizing film with added adhesive layer that is disposed, via a first adhesive layer and without interposing a conductive layer, to the first transparent substrate side on the viewing side of the in-cell liquid crystal cell. The polarizing film with added adhesive layer is provided with a surface treatment layer, a first polarizing film, and the first adhesive layer in this order, or is provided with the surface treatment layer, the first polarizing film, an anchor layer, and the first adhesive layer in this order. At least one layer selected from among the surface treatment layer, the anchor layer, and the first adhesive layer includes an antistatic agent. In this in-cell liquid crystal panel, the antistatic function is satisfactory and it is possible to satisfy touch sensor sensitivity as well as conduction reliability and durability in humid environments.
