One example of the present invention comprises: a first substrate; a cathode formed on the first substrate; an electron injection layer formed on the cathode; an electron transport layer formed on the electron injection layer; a light-emitting layer formed on the electron transport layer; a hole transport layer formed on the light-emitting layer; a hole injection layer formed on the hole transport layer; an anode formed on the hole injection layer; a wire-grid polarising plate in which a thin-film metal substance on the anode is alternately patterned at a first angle and at a second angle of 90 degrees to the first angle; and a second substrate placed on the wire-grid polarising plate.
