  • Patent number: 10890810
    Abstract: A display device includes substrates, pixels, an inter-pixel light blocking portion, a spacer, a spacer non-arranged portion, and a spacer arranged portion. The pixels are arranged in each of a first direction and a second direction perpendicular to each other. The inter-pixel light blocking portion includes at least one first partition portion partitioning the pixels arranged in the first direction and at least one second partition portion partitioning the pixels arranged in the second direction. The spacer is disposed between the substrates. The spacer non-arranged portion in which the spacer is not arranged is included in the first partition portion. The spacer arranged portion in which the spacer is arranged is included in the first partition portion. The spacer arranged portion wider than the spacer non-arranged portion has a formation area straddling the second partition portion with respect to the second direction.

  • Patent number: 7133013
    Abstract: An image display device includes a display device driving circuit having a scanning signal driving section for outputting display scanning signals according to display data with respect to respective scanning signal lines for displaying an image which is in accordance with the display data with respect to pixels which are disposed in a matrix, and the display device driving circuit includes a control section for controlling the output of the display scanning signals from the scanning signal line driving section to the respective scanning signal lines based on a transition instruction signal for making a transition of output of the display scanning signals to the respective scanning signal lines from successive output to simultaneous output so that the display scanning signals are simultaneously outputted to the plurality of scanning signal lines.
