Abstract:
1. A liquid crystal display device comprising: a plurality of pixels configured to be provided at an intersecting portion at which a plurality of column data lines intersects with a plurality of row scanning lines, in which two adjacent pixels that are connected to a same row scanning line are paired, each of the two pixels of each pairs individually including: a switching control unit configured to control the second switching unit to be turned off when writing and reading the pixels and control the second switching unit to be turned on when inspecting the pixels; a pixel control unit configured to perform, when writing and reading the pixels, for each of the subframe, an operation in which the subframe data is written into the first signal holding unit for each of the pixels per row in the plurality of pixels configuring the image display unit and the written data is applied to the pixel electrode; and an inspection control unit configured to alternately perform a first inspection operation in which an inspection signal is input from a first column data line connected to one pixel of the two pixels in each of the pairs into the one pixel and is read out to a second column data line connected to another pixel through the other pixel of the two pixels in each of the pairs and a second inspection operation in which an inspection signal is input from the second column data line into the other pixel and is read out to the first column data line through the one pixel, on all of the plurality of pixels in a unit of pixels in each row when the pixels being inspected.
