Hitachi Chemical Co. America, Ltd.

Liquid Type

Liquid-type applies to small- and medium-sized touch screens and for improving the visibility of large-sized LCDs.

Features

  • Higher Sensitivity → Shade part curing
  • Low Dielectric Constant → Improvement of touch panel
  • Low volume shrinkage → "Non - MURA”

〔Shade part curing〕


Equal curing including shaded part

〔Low volume shrinkage〕

Conventional Our products
Warpage of polarizer by resin shrinkage
(Cause of "MURA")
Less wapage of polarizer by low volume shrinkage (Non-"MURA")
