摘要： The present invention relates to a double-sided organic light-emitting display device capable of displaying images on both surfaces thereof. A double-sided organic light-emitting display device according to an embodiment of the present invention comprises: a first electrode layer for emitting electrons; a second electrode layer which emits holes and is disposed perpendicularly to the first electrode layer; an organic light-emitting layer interposed between the first electrode layer and the second electrode layer, and comprising multiple pixels so as to emit light at a portion where the first electrode layer and the second electrode layer intersect with each other, by the collision between the electrons and the holes; and a reflector unit formed in an arbitrary pattern which reflects, in the opposite direction, light transmitted through the first electrode layer or the second electrode layer, or a pattern reversed with respect to the arbitrary pattern, such that the multiple pixels display a first image on one surface in the arbitrary pattern, and display a second image on the other surface in the pattern reversed with respect to the arbitrary pattern.

摘要： Provided are a display device and a fabrication method thereof. The display device includes a first substrate and a second substrate having one surface opposite to one surface of the first substrate. The first substrate includes a first-one portion that overlaps the second substrate in a thickness direction and a first-two portion that does not overlap the second substrate. The second substrate includes a second portion that overlaps the first substrate in the thickness direction. The first-two portion has a greater thickness than the first-one portion. The second portion includes a second-one portion that overlaps the first-one portion in the thickness direction and a second-two portion disposed between the second-one portion and the first-two portion in a plan view. The second-two portion has a greater thickness than the second-one portion. The second-two portion is disposed so as not to overlap the first-two portion in the thickness direction.

摘要： The present invention relates to a stretched display panel fabricated by cutting an already-made display panel for displaying images, and a method for manufacturing the same. A method for manufacturing a stretched display panel according to an embodiment of the present invention is for the purpose of manufacturing a stretched display panel by cutting an already-made display panel comprising a color filter substrate and a TFT substrate into a desired size, and comprises the steps of: cutting the TFT substrate into a desired size; cutting the color filter substrate into a length smaller than that of the TFT substrate such that a pixel exposure portion is formed on the TFT substrate and exposes one or more horizontal pixel lines; forming a disconnection line on an end of the TFT substrate exposed by the pixel exposure portion so as to disconnect between a horizontal pixel line positioned on the end of the TFT substrate and an adjacent horizontal pixel line, thereby blocking inflow of electric noise through the horizontal pixel lines; and forming a reinforcement seal that reinforces rigidity of the pixel exposure portion concurrently with covering the pixel exposure portion by an encapsulation material so as to prevent a short circuit due to inflow of alien substances between the horizontal pixel lines. In the step of forming a reinforcement seal, a reinforcement material is applied while an application nozzle for applying the reinforcement material is arranged to slope from the end of the color filter substrate toward the end of the TFT substrate such that alien substances on the pixel exposure portion are pushed away and removed by the applied reinforcement material. Accordingly, the defect ratio can be minimized.
