Abstract: A display device includes a display panel, an adhesive layer on the display panel and comprising a plurality of layers having different loss modulus and glass transition temperatures Tg, a cover window on the adhesive layer, and an actuator at the cover window. Then, the adhesive layer includes a first adhesive layer having a lower loss modulus and a glass transition temperature Tg and a second adhesive layer having a higher loss modulus and a glass transition temperature Tg.

Abstract: In a multi-panel display device in which plural individual display devices are joined, it is possible to guarantee image continuity in panel junction areas of the multi-panel display device by disposing a frame-type optical member, which includes a frame section having plural optical fibers and a central light-transmitting area, on the front surface of the multi-panel display device and optimizing structures of an inner inclined surface of the frame section of the frame-type optical member and optical fibers included in the frame section.

Abstract: In a plate-type optical member for a multi-panel display device in which a plurality of individual display devices are joined and which includes junction area in which non-active areas of the individual display devices are arranged, the plate-type optical member includes plural optical fibers that have input ends opened to the lower part of the plate-type optical member and output ends opened to the upper part of the plate-type optical member and a resin support that supports the optical fibers. It is possible to guarantee image continuity in panel junction areas by disposing the plate-type optical member on the front surface of the multi-panel display device.
