The invention provides an ocular lens and a display device. The ocular lens comprises the components of a lens assembly with positive focal power or negative focal power, wherein the lens assembly comprises at least two lenses, in a direction of approaching an image source, a first lens and a second lens are successively arranged; a reflective linear polaroid which is arranged on one surface, which is next to the image source, of the first lens, or the surface of the second lens; a reflective circular polarid which is arranged on the surface of the first lens, wherein the reflective circular polaroid is arranged at one side, which is far from the image side, of the reflective linear polarid; and a quarter lambda wave plate which is arranged between the reflective liner polaroid and the reflective circular polaroid, wherein the first lens has positive focal power or negative focal power, the second lens has the negative focal power, the Abbe number Vd1 of the material of the first lensis higher than 50, and the Abbe number Vd2 of the material of the second lens is lower than 30. The ocular lens has advantages of relatively short working distance, relatively small lens size, low thickness of the lens and relatively high imaging quality.
