Abstract: A display device includes a first substrate having a first step part formed in a frame area on a periphery of a display area, a second substrate arranged facing the first substrate, and a filler material filled between the first substrate in one part of the display area and the frame area, and the second substrate, a periphery edge part being located in a range from the first step part to an end part of the first substrate and the second substrate.

Abstract: A sealing substrate is arranged to oppositely face an element substrate on which organic EL layers are formed in a matrix array with a sealing material sandwiched therebetween. A gel-state desiccant is filled in an inner space surrounded by the element substrate, the sealing substrate and the sealing material. Since the gel-state desiccant is in a gel state, the gel-state desiccant is flexibly filled in the inner space of the organic EL display device thus completely eliminating a gap. Since the inner space is filled with the gel-state desiccant, moisture hardly intrudes into the inner space from the outside and, at the same time, a mechanical strength of the organic EL display device is also enhanced.

Abstract translation: 密封基板被布置为相对地面对其上形成有有机EL层的元件基板，矩形阵列中夹有密封材料。 凝胶状干燥剂填充在由元件基板，密封基板和密封材料围绕的内部空间中。 由于凝胶状干燥剂处于凝胶状态，所以凝胶状干燥剂能够灵活地填充在有机EL显示装置的内部空间中，从而完全消除间隙。 由于内部空间填充有凝胶状干燥剂，因此水分几乎不会从外部进入内部空间，同时也增强了有机EL显示装置的机械强度。
