Abstract

An electroluminescence display device is provided in which a plurality of pixels are arranged in row and column directions, including: a gate line extending in the row direction; a first thin film transistor whose gate is connected to the gate line; a drain line extending in the column direction; a capacitor connected to the drain line via the first thin film transistor; a second thin film transistor whose control electrode is connected to the capacitor; and an EL element connected to a supply line via the second thin film transistor and having a luminescent layer between an anode and a cathode. The first thin film transistor is disposed in a region between the gate line and the capacitor.

Claims (9)

1. An electroluminescence display device in which a plurality of pixels are arranged in row and column directions, comprising:

a gate line extending in the row direction;

a first thin film transistor whose gate is connected to said gate line;

a drain line extending in the column direction;

a capacitor connected to said drain line via said first thin film transistor;

a second thin film transistor whose control electrode is connected to said capacitor; and

an EL element connected to a supply line via said second thin film transistor and having a luminescent layer between an anode and a cathode,

wherein said first thin film transistor is disposed in a region between said gate line and said capacitor,

wherein said first and second thin film transistors are disposed on opposite sides with said capacitor in a middle area between said first and second thin film transistors wherein said first thin film transistor is connected to one end of an electrode of said capacitor, and a gate of said second thin film transistor is connected to the other end of said electrode of said capacitor.
