Abstract
A protection tape for a printed circuit board (PCB) includes an insulating base plate, a conductive layer over the insulating base plate, and an adhesive layer over the conductive layer, the adhesive layer including a main part having a first thickness and a subsidiary part having a second thickness less than the first thickness, the main part corresponding to at least a center portion of the insulating base plate and the subsidiary part being arranged at an outside of the main part.
Claims20
A display device comprising:
- a display panel;
- a printed circuit board (PCB) electrically connected to the display panel;
- and
- a protection tape covering one surface of the PCB, wherein
- the protection tape comprises:
- an insulating base plate;
