Abstract

The present invention relates to an adhesive sheet for a display, and more particularly to an adhesive sheet for a display and a display including the same, that is, antistatic treatment can be performed to prevent generation of static electricity, and the failure rate can be significantly reduced when an attached material cannot be corroded. The adhesive sheet has excellent adhesion to the display device.

Description

Technical field [0001] The present invention relates to an adhesive sheet for a display, and more specifically to an adhesive sheet for a display and a display including the same, which can prevent the generation of static electricity by performing an antistatic treatment, and significantly reduce the failure rate without corrosion. The adhesive material has excellent adhesion to the display device. Background technique [0002] Recently, with the rapid development of information and communication technology and the expansion of the market, flat panel display devices (Flat Panel Display) have attracted much attention as display devices. Representative such flat panel display devices include liquid crystal display devices (Liquid Crystal Display), plasma display devices (Plasma Display Panel), organic light emitting devices (Organic Light Emitting Diodes), and the like. [0003] Organic light-emitting devices have advantages such as fast response speed, lightness, thinness and shor...
