Organic electro-luminescence display device and manufacturing method thereof

A method of manufacturing an organic electro-luminescence display device, comprising:

• providing a first substrate, wherein an organic light emission diode element and a contact spacer are disposed on the first substrate;
• disposing a sealant film of first sealant material on the first substrate;
• disposing a second substrate on the sealant film, wherein a driver element and a connection electrode are disposed on the second substrate, and the connection electrode is connected to the driver element;
• simultaneously applying a first heat and a pressure to the second substrate, to melt the sealant film and to fill the melted sealant film into a cavity, which is formed by the first and second substrates, the connection electrode, the organic light emission diode element, and the contact spacer;
• and
• applying a second heat to the second substrate during a fixed period and hardening the sealant film, to form a first sealant,
• wherein the first sealant is bonded to the contact spacer and the connection electrode and maintains the electrical connection between the contact spacer and the connection electrode.
