A reflective mirror array having smile mirrors that reflect a uniform image

摘要

The present invention relates to a reflective mirror array used in a projection display device, in which a first length in a direction in which each micro-mirror corresponding to a pixel is parallel to the incident surface of parallel light is longer than a second length in a direction perpendicular to the incident surface A reflective mirror array having a plurality of micro-mirrors with reflective surfaces. This type of reflective surface allows the shapes of each reflected image to be uniformly orthogonal to each other, despite the incidence angles provided by the respective micro-mirrors being different from each other. Therefore, the projection type display apparatus to which the reflective mirror array is applied does not require a separate image correction unit, so that the configuration of the optical system is simple and high optical efficiency is provided.
