A transparent electrode (4) is made of an electrically conductive material and has a plurality of linear portions (22) extending substantially parallel to each other, and at least a part of the linear portions (22) are electrically connected to each other. Preferably, the linear portions (22) are formed with a pitch therebetween of at most a wavelength of visible radiation, and the linear portions (22) are formed each with a width of at most one half of the pitch.
