Abstract: Provided is a display device with reduced interface reflection and high luminance. The display device includes: a display panel; and a front surface plate disposed closer to an observer side than the display panel is. The display panel in a plan view includes a display region and a frame region surrounding the display region. The front surface plate in a plan view includes a design layer that overlaps the display region. The front surface plate transmits at least part of light incident from the display panel and reflects at least part of light incident from the observer side. A transmittance of a region of the front surface plate overlaps the display region being 50% or higher. The front surface plate and the display panel are attached to each other with an optical adhesive layer. A refractive index of the optical adhesive layer is 1.4 or higher and 1.6 or lower.
