Abstract: A display device includes: a substrate; a display area including pixels arranged on the substrate; a first area disposed at one side of the display area; a second area including pads arranged on the substrate; a bending area disposed between the first area and the second area; and a fan-out line disposed in the first area, the bending area, and the second area. The fan-out line includes: a plurality of sub-routing lines arranged in the first area and electrically connected to each other; and a plurality of sub-pad lines arranged in the second area and electrically connected to each other. The number of the plurality of sub-routing lines is greater than the number of the plurality of sub-pad lines.

Abstract: The present invention relates to a method for preparing dimethylether from methanol using a membrane reactor, more particularly to a method for preparing dimethylether from methanol using a membrane capable of carrying out a reaction and a separation at the same time while preparing dimethylether from methanol. Because water vapor generated by dehydration of methanol can be selectively removed from the catalytic reaction zone, decrease in catalytic activity can be prevented and thus life span of a catalyst can be extended. Further, reaction efficiency can be improved even at a temperature milder than the conventional one for dimethylether preparation, and also additional steps of separation and purification after completion of the reaction is no longer necessary.
