  • Patent number: 11963410
    Abstract: A display device includes a substrate including a pixel region and a peripheral region. A plurality of pixels is disposed in the pixel region of the substrate. Each of the plurality of pixels includes a light emitting element. Data lines and scan lines are connected to each of the plurality of pixels. A power line is configured to supply power to the plurality of pixels. The power line includes a plurality of first conductive lines and a plurality of second conductive lines intersecting the plurality of first conductive lines. The plurality of second conductive lines is arranged in a region between adjacent light emitting elements of the plurality of pixels. At least some of the plurality of second conductive lines extend in a direction oblique to a direction of extension of the data lines or the scan lines.

  • Patent number: 9634024
    Abstract: A semiconductor device is provided. Word lines are formed on a substrate. An air gap is interposed between two adjacent word lines. A channel structure penetrates through the word lines and the air gap. A memory cell is interposed between each word line and the channel structure. The memory cell includes a blocking pattern, a charge trap pattern and a tunneling insulating pattern. The blocking pattern conformally covers a top surface, a bottom surface, and a first side surface of each word line. The first side surface is adjacent to the channel structure. The charge trap pattern is interposed only between the first side surface and the channel structure.
