Abstract: The present invention provides a novel compound that can improve the luminous efficiency, stability and life span of the element, an organic electronic element using the same, and an electronic device thereof.

Abstract: The present invention relates to: a message display method according to an event occurrence in a virtual reality (VR) device, wherein, when an event such as a telephone call, a text receipt such as an SMS, and a message receipt using a messenger program or an application occurs, during the displaying of a stereoscopic image through a head mounted display (HMD)-based VR device, in a communication terminal such as a smart phone combined with the VR device, a message according to an event occurrence is displayed by linking with a screen of the stereoscopic image being currently reproduced, thereby solving problems of severe discomfort sensation, which have occurred in conventional methods in which a message according to an event occurrence is displayed in a shape such as a black-based bar or box distinctly different from the stereoscopic image being currently reproduced, and thus is seen as an error message; and an apparatus therefor.
