  • Patent number: 10739694
    Abstract: In a case where a cleaning member is reciprocated in a longitudinal direction of a transmissive member in cleaning operation, the time necessary for the cleaning operation is lengthened. A movement unit is controlled to move the cleaning member in a first direction from a first position in response to a cleaning start signal and then to stop the cleaning member at a second position, and to move the cleaning member in a second direction opposite to the first direction from the second position in response to a next cleaning start signal and then to stop the cleaning member at the first position.

  • Patent number: 9885895
    Abstract: An image display device, and a production method thereof are provided, which maximize suppression of warping of a protective panel. A liquid crystal display panel and a transparent protective panel formed from a plastic are arranged facing each other via a cured resin. An outer dimension of the protective panel is made larger than an outer dimension of the display panel. Curing is carried out with an edge of the protective panel fixed with a fixing jig during and after curing. Alternatively, the outer dimension of the protective panel is substantially equal to an outer dimension of the display panel, which is substantially equal to an inner dimension of a case and the protective panel. Curing is carried out with the resin composition in contact with substantially the whole face of the protective panel.
