Organic light emitting diode display device

An OLED display device, comprising:

• a first substrate;
• a second substrate opposite to the first substrate and has a first side;
• an organic light emitting layer disposed between the first substrate and the second substrate;
• and
• a glass-forming sealant disposed between the first substrate and the second substrate and being adjacent to the first side,
• wherein the glass-forming sealant has:
• a first end connecting to the first substrate and being apart from the first side in a first distance;
• a second end connecting to the second substrate and being apart from the first side in a second distance;
• and a third end locating between the first end and the second end and being apart from the first side in a third distance, wherein the first distance is unequal to the second distance, and the third distance is shorter than the first distance or the second distance.
