ABSTRACT:
An image display apparatus is disclosed which includes: an optical system including a light source and at least one projection lens; a display means for forming a display image, the display means including a non-luminescent display panel and a microlens array disposed on the light-incidence side of the display panel; and at least one projection lens for projecting the display image; wherein the display panel and the microlens array are combined with each other by means of an adhesive made of a transparent material. In cases where the microlens array is provided with color filters which are arranged so as to correspond to the microlenses of this array, the image display apparatus can provide a bright display of color images with an improved contrast. Moreover, when the display panel and the microlens array are combined with each other by means of an adhesive containing spacers, the image display apparatus has a high thermal reliability.
