Abstract
A plasma generation device forms a patterned adhesive layer on a separation sheet surface and includes a roller part and plasma generator. The roller part includes a transfer roller for transferring the separation sheet and a metal member embedded in the transfer roller. The plasma generator includes a main body, electrode members, and a guide member. The main body is configured to be spaced from the transfer roller and elongated in a width direction perpendicular to a transfer direction of the separation sheet. The electrode members are disposed in the width direction and generate plasma on only a separation sheet surface disposed facing the metal member to form the patterned adhesive layer. The guide member fixes the electrode members to the main body and is detachably coupled to the main body to fix the electrode members to or separate the electrode members from the main body at the same time.
