A display device includes a first supporting member disposed in the first pad area of the first base substrate and spaced apart from the sealing member to define a predetermined space. A second supporting member is filled in the predetermined space by filling and curing liquid material. This protects the display panel from harsh ambience, such as light, heat and moistures, reducing the sealing and black matrix area. Such improvement can decrease the bezel size, effectively increasing viewable area of the display, which becomes more important in the mobile device.
