Touch window having improved electrode pattern structure

A touch device comprising:

• an organic light emitting device;
• a touch window on the organic light emitting device;
• the touch window comprising:
• a cover window;
• a base substrate;
• a first sensing electrode formed on a view area (V/A) of the base substrate and comprising first unit cell electrode patterns and a first lead electrode connecting two first unit cell electrode patterns to each other;
• a second sensing electrode which crosses the first sensing electrode formed on the view area (V/A) of the base substrate and comprising second unit cell electrode patterns and a second lead electrode connecting two second unit cell electrode patterns to each other;
• a first space part between one first unit cell electrode pattern and two second unit cell electrode patterns adjacent to the one first unit cell electrode pattern;
• a dummy pattern which is not received a touch input formed in the first space part;
• wherein a ratio of an area of the first space part to an area of the one first unit cell electrode pattern is in a range of 10% to 20%;
• and
• wherein the first sensing electrode and the second sensing electrode are both disposed on the same surface of the base substrate.
