Title:
IN-CELL LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/181478
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 comprising liquid crystal molecules which are homogeneously oriented when no electric field is present, 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. The surface treatment layer includes at least one of any antistatic agent selected from ionic surfactants, conductive microparticles, and conductive polymers. 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.
