Embodiments provide a display device including: a thin film transistor disposed on an insulation substrate including a plurality of pixels; a common electrode and a pixel electrode disposed on the thin film transistor to overlap each other while interposing an insulating layer therebetween; a liquid crystal layer filling microcavities differentiated by pixel electrodes, the pixel electrodes comprising the pixel electrode; and a roof layer that is disposed on a microcavity of the microcavities and includes an injection hole extending to the microcavity and a supporting member to support the microcavity; and an optical member disposed on the supporting member, wherein the injection hole is disposed between adjacent microcavities in a column direction, and the supporting member is disposed between adjacent microcavities in a row direction. Total reflection of light, bad alignment, and light leakage which may occur in the display device may be prevented by the optical member.
