A display apparatus includes a display panel supported within a case having a rear surface including a circular recessed portion. An annular total reflection mirror and an annular half mirror are disposed in the circular recessed portion with an annular light source provided therebetween. A pattern forming member is disposed on an outer side of the annular half mirror and is configured to be reflected by the annular total reflection mirror. A pattern light source is configured to supply light to the pattern forming member so that the pattern is reflected on the annular total reflection mirror. When the annular light source and the pattern light source are turned on, the pattern of the pattern forming member is reflected between the annular total reflection mirror and the annular half mirror.
