Abstract
The invention relates to a display device including a plurality of pixels forming an image, and an optical plate arranged opposite the image and having transparency areas configured to allow the light from the pixels to at least partially pass therethrough. The optical plate further includes at least one array of functional elements corresponding to an electronic and/or mechanical function. The functional elements are inserted between the transparency areas and arranged such that the light emitted by the pixels is directed so as to pass through the transparency areas without intercepting the arrays of functional elements, so as to render the arrays of functional elements invisible or quasi-invisible to an observer of the display device. The invention can be used in any type of display device in which functions other than display itself must be integrated in a visually discreet manner.
