PROBLEM TO BE SOLVED: To provide an EL element advantageous in improving light extraction efficiency by optimizing light extraction efficiency; a display; a display device; and a liquid display device. SOLUTION: A microlens sheet 7 is provided on a surface of a first transparent substrate 1A via an adhesive layer 6, wherein the surface is on an opposite side of a surface of the first transparent substrate 1A facing a positive electrode 3. The microlens sheet 7 has a surface facing an opposite side of the first transparent substrate 1A and micro unit lenses 5 arranged on the surface. The microlens sheet 7 is formed so as to have a region satisfying formula (1) of 0.3≤(T1/P1)≤(S1/S2), where P1 is an average diameter of the micro unit lenses 5, T1 is an average height of the micro unit lenses 5, S1 is the total of bottom areas of the micro unit lenses 5, and S2 is an area of a remaining part except for S1 of the surface.
