  • Publication number: 20240105123
    Abstract: A display apparatus with improved light emission uniformity includes a pixel. The pixel includes a driving thin-film transistor (TFT); a storage capacitor; a driving semiconductor layer; a first electrode layer; a second electrode layer; a pixel electrode; a pixel-defining layer defining a light-emitting region; and a conductive layer interposed between the first electrode layer and the pixel electrode and including an extending portion that at least partially overlaps the light-emitting region in a plane view to pass over a central portion of the light-emitting region.

  • Patent number: 8465733
    Abstract: Disclosed are a method for producing a frozen pharmaceutical composition prepared from cultured human mesenchymal stem cells and a pharmaceutical composition containing human mesenchymal stem cells. This method is a method for producing a frozen pharmaceutical composition containing human mesenchymal stem cells, which comprises the following steps in this order: (a) adding trypsin to human mesenchymal stem cells in a culture vessel to detach the cells from the surface of the culture vessel; (b) adding a bicarbonate Ringer's solution containing human serum albumin to the detached cells to terminate the reaction with trypsin, and washing the cells with the bicarbonate Ringer's solution containing human serum albumin; (c) suspending the cells in a bicarbonate Ringer's solution containing human serum albumin and dimethyl sulfoxide; (d) putting the resulting suspension in a container which allows freezing of what is contained therein, and sealing the container; and (e) freezing the suspension put in the container.
