Light emitting panel assemblies include one or more light emitting panel members each having at least one pattern of optical deformities that may be varied in size, shape, density, placement, angle, rotation and/or type to obtain at least one light output distribution having a form or shape of at least one of text, graphics, logo or image. At least some of the optical deformities may be shaped or oriented preferentially to cause different colored light propagating through the panel member in different directions to create a multi-colored light output distribution. Also, a plurality of panel members each having a different light output distribution may be placed in overlying relation to one another to produce a composite output distribution when viewed through the panel members or a display overlying the panel members.
