  • Publication number: 20240334782
    Abstract: A display device includes a substrate, a circuit layer, a light emitting element layer, a sealing layer, and a polarization layer. A main area of the substrate includes a display area including emission areas and a non-display area disposed around the display area, the non-display area includes a dam area spaced apart from the display area, the dam area including at least one dam portion surrounding the display area. The non-display area also including a bonding area that surrounds the dam area, the circuit layer includes a buffer portion disposed in a part of the bonding area adjacent to the sub-area, the buffer portion being spaced apart from each of the sub-area and the dam area, and the polarization layer extends to the non-display area and overlaps the buffer portion.

  • Publication number: 20110120192
    Abstract: The fluid balancer includes balancer housings in which ring-shaped flow chambers partially filled with a fluid are provided, and a plurality of guides disposed in the flow chambers and separated from each other in the circumferential direction of the flow chambers. The plurality of guides is provided with first communication holes provided on inner peripheral sides of the balancer housings and second communication holes provided on outer peripheral sides of the balancer housings, and the performance of the fluid balancer is improved by adjusting an area of the second communication holes and a volume filling each of the flow chambers.
