Abstract: A display device includes a base substrate, a light emitting element disposed on the base substrate, an inorganic layer disposed on the light emitting element and including a metal and a metal oxide layer, an encapsulation layer disposed on the inorganic layer, an organic layer disposed on the encapsulation layer and including a quarter-wave plate, and an anti-reflection layer disposed on the organic layer.

Abstract: An advertisement mediating system includes: a communicator configured to receive, from a first device, information about content into which an advertisement is to be inserted and information about an inventory included in the content, and transmitting, to one or more second devices, the information about the content and the information about the inventory; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, wherein the processor is configured to execute the one or more instruction to perform, when a request for inserting the advertisement into the inventory is received from the one or more second devices, a control operation of selecting advertisement content from among a plurality of pieces of advertisement content corresponding to the one or more second devices, receiving the selected advertisement content, and transmitting the advertisement content to a third device that executes the content.

Abstract: A display device includes a display panel, a filler layer, a reflection control layer, a plurality of light-blocking patterns, and an encapsulation substrate. The low reflection layer is disposed on the display panel. The filler layer is disposed on the display panel. The reflection control layer includes a first catalyst and is disposed on the filler layer. The plurality of light-blocking patterns is disposed between the filler layer and the reflection control layer. The encapsulation substrate is disposed on the reflection control layer.

Abstract: Provided is a percutaneous screw fixing rod inserting device for minimal invasive surgery, which includes: a leg unit including a plurality of support legs, each of which has a joint link provided at a lower end thereof; an aligning holder unit configured to align the plurality of support legs such that longitudinal central axes of the support legs of the leg unit are placed on one virtual plane, the aligning holder unit holding the support legs such that an angle between the longitudinal central axes of the support legs is maintained; and a rod inserting unit coupled to the aligning holder unit to rotate by a predetermined angle around a portion coupled to the aligning holder unit and configured to insert the rod into a rod insert hole provided to the joint link of the support leg, thereby eliminating the difficulty of inserting the rod caused by the misalignment of the pedicle screws and increasing the convenience or efficiency of the medical procedure.
