Abstract
The invention provides an optical lens including a first lens, a second lens, a third lens, a fourth lens, and a fifth lens with refracting power in order from a light incidence side to a light-emitting side along an optical axis, and at least one glass lens is included. The first lens has a positive refracting power, the second lens has a positive refracting power, and the third lens has a negative refracting power. The optical lens satisfies a condition of 0.5EFL<EFL<2EFL, where EFL is an effective focal length of the optical lens, and EFLis an effective focal length of the at least one glass lens. The optical lens is adapted for receiving an image beam from the light incidence side, and the image beam forms a stop on the light-emitting side after passing through the optical lens. A display device is also proposed.
