Abstract

An organic electroluminescence display device includes: a TFT substrate on which organic electroluminescence elements are formed; a color filter substrate having a color filter layer; a fill material with which the TFT substrate is stuck onto the color filter substrate; a dam material that dams the fill material in a non-display area; and a gas barrier film made of an inorganic material which is arranged between the fill material and the color filter layer, covers the display area in a plan view, and is formed at an interval from the dam material in the non-display area in an inside of the dam material.

Claims (17)

1. An organic electroluminescence display device, comprising:

a TFT substrate on which organic electroluminescence elements are formed in respective pixels of a display area;

a color filter substrate having a color filter layer in which color filters are formed in correspondence with the respective pixels;

a fill material with which a side of the TFT substrate on which the organic electroluminescence elements are formed is stuck onto a side of the color filter substrate on which the color filter layer is formed;

a dam material that dams the fill material in a non-display area in an outside of the display area; and

a gas barrier film made of an inorganic material which is arranged between the fill material and the color filter layer, covers the display area in a plan view, and is formed at an interval from the dam material in the non-display area in an inside of the dam material.

2. The organic electroluminescence display device according to claim 1 ,

wherein an overall outer periphery of the gas barrier film is located in an inside of an inner periphery of the dam material in the plan view.

3. The organic electroluminescence display device according to claim 1 ,

wherein an interval between the dam material and the gas barrier film is set to be equal to or larger than 0.05 mm, and equal to or smaller than 1.0 mm.

4. The organic electroluminescence display device according to claim 1 , further comprising: a light shielding film made of an organic material which is arranged to surround an outside of an outer periphery of the color filter layer in a plan view, in the non-display area,

wherein the light shielding film comes in contact with the dam material.

5. The organic electroluminescence display device according to claim 1 ,

wherein an overcoat film made of an organic material is formed between the color filter layer and the gas barrier film.

6. The organic electroluminescence display device according to claim 5 ,

wherein an outer periphery of the overcoat film is located in an inside of the inner periphery of the dam material in the plan view, in the non-display area, and

wherein an area between the outer periphery of the overcoat film and the inner periphery of the dam material overlaps with an area between an outer periphery of the gas barrier film and the inner periphery of the dam material in the plan view.
