Abstract: A display device for a head-mounted display includes a first display panel and a second display panel that are arranged in parallel. The first display panel and second display panel each include a pair of substrates having a plane sectioned into a display region and a non-display region, and a columnar spacer interposed between the substrates. The substrate includes a spacer lightproof portion placed over the spacer. The first display panel and second display panel do not coincide with each other with regard to a location where the spacer lightproof portion in the display region is disposed.
