Abstract: A display device comprising: first and second pixels; a first data line connected to the first pixel and configured to have data voltages applied thereto; and a second data line connected to the second pixel, the second data line being adjacent to the first data line, and configured to have the data voltages applied thereto, wherein the first data line includes a 1A-th data line which is in a first data layer, and the second data line includes a 2B-th data line which is in a second data layer different from the first data layer.

Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.
