Display device and mobile terminal

A display device comprising:

• a display area having pixels arranged in a matrix;
• a vertical drive circuit for selecting pixels in the display arean in unit of rows;
• a first horizontal drive circuit receiving as input first and second digital image data, converting the digital image data to analog image signals, and supplying the same to a data line to which pixels of the row selected by the vertical drive circuit are connected;
• and
• a second horizontal drive circuit receiving as input a third digital image data, converting the digital image data to an analog image signal, and supplying the same to a data line to which pixels of the row selected by the vertical drive circuit are connected, wherein
• the first horizontal drive circuit includes a first sampling latch for sequentially sampling and latching the first digital image data,
• a second sampling latch for sequentially sampling and latching the second digital image data,
• an output circuit for selecting the first and second digital image data latched in the first and second sampling latches in a time division manner in a predetermined period and outputting the same,
• a digital/analog conversion circuit (DAC) for converting the first and second digital image data output from the output circuit to analog image signals, and
• a line selector for selecting the first and second digital image data converted to analog data by the DAC in a time division manner in the predetermined period and outputting the same to a data line.
