Disclosed is a liquid crystal display device which comprises first and second transparent substrates disposed one above the other, and a liquid crystal layer disposed therebetween and having pixels. The second transparent substrate includes a microlens array therein, which has microlenses for converging light on the respective pixels. The microlenses are so positioned that their focal points are located in the vicinity of the inner surface of the second transparent substrate, which is the surface on the side provided with the liquid crystal layer. Since the microlens array is included in one of the two transparent substrates, the focal length of each microlens can be made shorter, resulting in an improved effective aperture ratio.
