Abstract: An electroluminescent display device includes an electroluminescent display device includes a substrate; a first pixel row on the substrate including a first plurality of pixels arranged along a first direction; a second pixel row on the substrate including a second plurality of pixels arranged along the first direction, the second pixel row being spaced apart from the first pixel row in a second direction; a first groove between the first and second pixel rows; and a light emitting diode in each pixel of the first and second pixel rows, wherein the first groove includes a first portion at one end of the first pixel row, a second portion at the other end of the first pixel row and a third portion between the first and second portions, and wherein third portion is smaller than the first portion and greater than the second portion.

Abstract: Disclosed herein is a polishing pad having a substrate woven in a network form, capable of adsorbing dust generated during polishing of an object into meshes formed in the substrate to discharge the adsorbed dust to an external dust suction system or receive the dust in the meshes in a pocket form, in turn improving polishing efficiency of the polishing pad. In addition, polishing yarns are solidly adhered to a face part with relatively wider area on one side of the substrate so as to enhance durability of the pad.
