Abstract
An organic light emitting diode display device is provided, which comprises: a first substrate; a second substrate opposite to the first substrate; 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 around the organic light emitting layer. Herein the glass-forming sealant comprises: a first portion adjacent to the first substrate, and a second portion adjacent to the second substrate. A first angle is included between the first portion and the first substrate, which is smaller than 90°; a second angle is included between the second portion and the second substrate, which is smaller than 90°; and the first angle is different from the second angle.
