摘要： An electronic apparatus includes an electronic panel including a plurality of pads, a circuit board including a plurality of leads, and a conductive adhesive member configured to electrically connect the circuit board and the electronic panel. The plurality of pads include a plurality of pixel pads, an arrangement pad, and a resistance measurement pad disposed between the arrangement pad and the pixels pads and insulated from the pixel pads. The plurality of leads include a plurality of pixel leads, an arrangement lead, and a resistance measurement lead disposed between the pixel leads and the arrangement lead and insulated from the pixel leads. The resistance measurement lead includes a plurality of resistance measurement leads disposed between the arrangement lead and the pixel leads and electrically connected with the resistance measurement pad, and a dummy lead spaced apart from the plurality of resistance measurement leads in a plan view.
