Abstract:
A liquid crystal display element comprising:a liquid crystal layer; a pixel electrode portion having a plurality of pixel apertures for transmitting light; and at least one microlens array having a plurality of microlenses arranged in a two-dimensional form on at least one of a light incident side and a light emergent side of said liquid crystal layer corresponding to said pixel apertures, wherein each of said microlenses comprises: a light-collecting lens having at least one lens surface in the optical axis direction for collecting incident light toward corresponding one of said pixel apertures, the light-collecting lenses of the plurality of microlenses being continuous in the two-dimensional form; and a field lens having at least one lens surface in the optical axis direction so that the focal position thereof substantially coincides with the principal point of said light-collecting lens, the field lenses of the plurality of microlenses being continuous in the two-dimensional form.
