DISPLAY DEVICE AND METHOD FOR PROCESSING DATA IN DISPLAY DEVICE

A display device employing a field sequential system is realized, that can transfer video data for field sequential among a plurality of substrates through a general standard interface. In a display device including a first circuit substrate (10) having a signal processing circuit (100), and a second circuit substrate (20) having liquid crystal timing controllers (200), the signal processing circuit (100) is provided with a signal separation circuit (110) configured to separate an input image signal (DIN) for one frame period into first intermediate data on a field basis, and a rearrangement circuit (120) configured to convert the first intermediate data to second intermediate data having a format depending on a standardized interface, and to rearrange the second intermediate data so that data for a plurality of rows is simulatively put together as data for one row, by which field data is generated.
