An accessory 1 is mounted on a board 2, and a connector main portion 31 is formed by terminals 5 and a connector board 6, and one end portions of the terminals 5 are soldered to the board 2. The elliptical polarizer comprises at least a first polarizer, a first optically anisotropic layer, a second optically anisotropic layer, and a third optically anisotropic layer, laminated in this order, the first optically anisotropic layer satisfying 1 50\u2266Re1\u2266500, 2 30\u2266Rth1\u2266750, and 3 0. A channel having the largest load current is connected to a wiring line that is least likely to radiate noise and, as a result, radiation noise is further reduced.
