Abstract: Discussed are a light-emitting device and a light-emitting display device having improved efficiency and increased lifespan. A plurality of stacks is provided between an anode and a cathode for at least a subpixel to emit a predetermined color, and emissive layers in different stacks include the same color-based materials having different luminous properties.

Abstract: Discussed is a light emitting display device which enables a common layer having high hole conductivity among common layers in respective stacks to include a material having a high orientation factor value so as to prevent generation of leakage current between subpixels and ensure high efficiency and a long lifespan.

Abstract: Disclosed is a light emitting display device which prevents pixel shrinkage and improves reliability by changing the structure of a bank and the inner structures of light emitting devices outside an active area of the light emitting display device.

Abstract: Disclosed herein is a system and method for extracting users of similar interests between various types of web servers. The system includes a user profile vector creation unit, a user similarity calculation unit, and a similar user extraction unit. The user profile vector creation unit collects tag data, performs standardization calculation on the degree of importance of each of one or more tags, and creates user profile vectors for respective users. The user similarity calculation unit calculates user similarity using the user profile vectors of the respective users created through the user profile vector creation unit. The similar user extraction unit extracts users of similar interests using the value of the user similarity calculated through the user similarity calculation unit.
