Active matrix type electroluminescence display device

An active matrix type electroluminescence display device comprising:

• a plurality of display pixels arranged in rows and columns in a matrix form;
• gate signal lines, each of which is connected to and shared by a plurality of display pixels provided on each row;
• gate drive circuits for sequentially supplying select signals to said gate signal lines;
• a data line is provided for each column;
• and
• a data signal is provided to each of said columns from only one end of said data line;
• wherein
• each of said display pixels includes an electroluminescence element, a first thin film transistor in which a display signal is applied to the drain and which is switched on and off in response to said select signal, and a second thin film transistor for driving said electroluminescence element based on said display signal;
• and
• said gate drive circuits are placed so that said select signals are supplied from both ends of said gate signal lines to said gate signal lines, each of said gate signal lines is connected to said gate drive circuits at both ends of said gate signal lines.
