A projection display apparatus using a microlens array and a micromirror array comprises a substrate, multiple micromirror arrays and multiple microlens arrays. The substrate is disposed apart with a predetermined distance from a light source. The multiple micromirror arrays are disposed over the substrate to be assembled together to have a predetermined incidence angle with respect to the incident rays. The multiple microlens arrays are configured to correspond to the micromirror arrays. More specifically, a first microlens array is disposed in a predetermined region between the light source and the substrate and comprises multiple microlenses. A second microlens array is disposed in a light path of reflection rays reflected from the micromirrors.

A method of fabricating a polymer or resist pattern over a substrate includes coating a photosensitive polymer or resist over the substrate to form a polymer or resist layer, determining a portion of the polymer or resist layer to be exposed to light, placing a light adjusting layer in an optical path of light shone on the polymer or resist layer, and adjusting the light adjusting layer to adjust a direction or intensity of the light shone on the polymer or resist layer. Based on the method, it is easy to fabricate a polymer or resist pattern, a metal film pattern, metal pattern structure, and a polymer mold, each having three-dimensional structures with various slopes or shapes by adjusting a direction or intensity of incident light when performing a lithography process.

Disclosed are a micromirror device made in a simple structure using interdigitated cantilevers and having two stable rotational states, and applications thereof. The micromirror device comprises: (a) a substrate; (b) at least two protruded support posts arranged protrudedly in two columns of left and right sides on the substrate and apart by a predetermined interval from each other; (c) multiple cantilevers formed in parallel with the substrate, each having one end attached at the upper end portion of the respective protruded support posts and made in a thin strip having an elastic restoring force, wherein the cantilevers adjacent to each other are arranged to be parallel and interdigitated; (d) mirror support posts coupled to upper portions of the other ends of the cantilevers; (e) a mirror attached on upper portions of the whole mirror support posts and supported by the mirror support posts; and (f) two electrodes formed at left and right sides on the substrate, for providing an electrostatic force to the mirror, wherein the micromirror device reflects light incident into the mirror in different directions from each other by using an electrostatic force due to a voltage applied between the electrodes and the mirror, and the elastic restoring force of the cantilevers. The micromirror device can drive the mirror in two directions and adjust a rotational angle of the mirror using the electrostatic force due to a potential difference between the electrodes and the mirror for reflecting incident light, and the elastic restoring force of the cantilevers.

An embodiment of the present invention relates to a digital micromirror device. More particularly, an embodiment of the present invention relates to a method of manufacturing a digital micromirror device having a perfectly flat mirror surface, wherein a hole of a mirror surface from which light is reflected is obviated by forming a mirror support post portion using an electro-plating process, unlike the related art digital micromirror device in which the hole is formed at the center of the mirror surface, thereby degrading the reflection efficiency of light.
