摘要： A method of manufacturing a curved display panel by reducing a thickness of a flat display panel comprising a first substrate and a second substrate, the method includes: polishing a portion that is to form a protrusion on an edge of at least one of the first substrate and the second substrate to a preset thickness through mechanical polishing; masking the portion that is to form the protrusion, polished to the preset thickness in the polishing, using a masking member so as to prevent the portion from being etched by an etchant; and etching the display panel to a preset thickness by the etchant so as to be thinner than the portion masked by the masking member to make the protrusion protrude therefrom.

摘要： A method of manufacturing a curved display panel, includes: polishing a portion of the flat display panel that is to form a protrusion, which protrudes in order to protect a portion, to which a drive circuit board is attached, through mechanical polishing so as to have a preset thickness; installing a sealing member, which protects the flat display panel, polished in the polishing, from an etchant by surrounding both the portion that is to form the protrusion and the drive circuit board; and etching an entirety of both surfaces of the flat display panel using the etchant, excluding a portion on which the sealing member is provided, so that the flat display panel, having the sealing member installed in the installing, has a thickness smaller than a thickness of the protrusion.

摘要： A method of manufacturing a stretched display panel includes: cutting the TFT substrate to a desired size; cutting the color filter substrate; forming an open-circuit line for open-circuiting a portion defined between a horizontal pixel line that is located at an end of the TFT substrate and another horizontal pixel line adjacent thereto in order to prevent electrical noise due to the horizontal pixel lines being introduced into the end of the TFT substrate exposed from the pixel exposure portion; and forming a reinforcement seal for covering the pixel exposure portion using a reinforcement material in order to prevent occurrence of short circuit due to introduction of foreign matter into a gap defined between the horizontal pixel line and the other horizontal pixel line and at the same time to increase rigidity of the pixel exposure portion.

摘要： A three-dimensional image device for providing an improved sense of immersion includes: a moving stage that includes a seat on which a viewer sits and a seat moving mechanism for moving the seat; a first transparent curved display located in front of the viewer and having a curved surface shape that is concave in the direction in which the viewer watches the first curved display, wherein the seat moves according to a first displayed image; and a second curved display located behind the first curved display and having a curved surface shape that is concave in the direction in which the viewer watches the second curved display, wherein the second curved display displays a second image overlapping the first image. Accordingly, it is possible to enhance the three-dimensional effect of a three-dimensional image, to increase a sense of immersion, and to improve a sense of realism.

摘要： A digital bezel of a display device includes: a display device including a bezel region for displaying an image different from an effective screen by dividing a frame portion of an effective screen of the display device; and an optical pick-up member, mounted in the bezel region, for picking up an image displayed in the bezel region in a straight line by a predetermined thickness to three-dimensionally highlight the image. As such, the three-dimensional effect of the image can be emphasized and manufacturing costs can be reduced.
