Abstract: The present disclosure relates to a smart pen and a display device using the same, in which a reflective light reception rate may be enhanced through a light output structure to increase a code pattern and code information recognition rate of a display panel. According to an embodiment of the disclosure, smart pen comprising a body portion, a pen tip portion formed on one end of the body portion to form a path of light emitted from a light emitting portion in an end direction at one side, a code detector detecting shape data for code patterns by applying light to the pen tip portion and receiving light reflected from a display panel and the pen tip portion, and a code processor generating coordinate data by using the shape data and transmitting the coordinate data to a main processor for driving the display panel.

Abstract: A flexible window includes: a first film layer through which light is incident to the flexible window from a display panel of a flexible display device, the first film layer including: a plurality of stacked first sub-film layers, an adhesive layer disposed between adjacent first sub-film layers, and an index matching layer disposed between a first sub-film layer and the adhesive layer adjacent thereto; and a second film layer on the first film layer to be disposed further from the display panel than the first film layer, the second film layer having a Young's modulus lower than that of each of the first sub-film layers. Within the flexible window, a refractive index of the index matching layer has a value between a refractive index of each of the first sub-film layers and a refractive index of the adhesive layer.

Abstract: A display device has excellent luminous efficiency, the display device including: a display portion including pixels defined by a pixel defining layer; and a touch portion on the display portion. The touch portion includes: a first touch electrode overlapping the pixel defining layer; a first organic layer on the first touch electrode; a second touch electrode contacting the first touch electrode; a second organic layer on the second touch electrode; and a high refractive index layer on the first organic layer, the second touch electrode, and the second organic layer. The high refractive index layer is disposed between adjacent second touch electrodes in a plan view and includes a first convex surface protruding toward the display portion and overlapping one of the pixels.
