Abstract

The present invention relates to a touch sensor integrated with an upper plate of a liquid crystal panel and, more particularly, to a touch sensor integrated with an upper plate of a liquid crystal panel comprising: a photo-alignable separation film; a liquid crystal driving electrode disposed on the photo-alignable separation film; and a transparent electrode laminate disposed on the liquid crystal driving electrode. Accordingly, the touch sensor of the present invention does not need a separate liquid crystal panel upper substrate, and thus has a remarkably reduced thickness such that an ultra-thin film can be realized, or the touch sensor can be usefully applied to a flexible touch screen panel.
