Organic EL display device and method for fabricating the same
An organic EL display device and a method for fabricating the same are disclosed, wherein an organic luminescence layer is formed at a crossing region of first and second electrodes using a shadow mask on which a plurality of holes are connected by bridges.
1. A mask for fabricating organic luminescence layer of an organic electroluminescence display device, comprising:
a plate having a plurality of holes, wherein the holes are formed as a striped shape extending in a column direction;
a first plurality of bridges crossing each of the holes along a first row direction; and
a second plurality of bridges crossing each of the holes along a second row direction,
wherein each of the bridges are formed on a different plane than the plate and a thickness of each of the bridges is substantially equal to a thickness of the plate, wherein lower surfaces of each of the bridges are on upper surface of the plate and wherein the plurality of holes define deposition areas on the organic electroluminescence display device on which material is to be deposited.
2. The mask of claim 1 , wherein the bridges have their width and thickness in the range of 1˜1000 μm.
3. A mask for fabricating organic luminescence layer of an organic electroluminescence display device, comprising:
a plate having a plurality of holes each having a width, wherein the holes are formed as a striped shape extending in a column direction;
a first plurality of bridges crossing each of the holes along a first row direction; and
a second plurality of bridges crossing each of the holes along a second row direction,
wherein each of the bridges are formed on a different plane than the plate and a thickness of each of the bridges is substantially equal to a thickness of the plate, wherein lower surfaces of the each of bridges are on upper surface of the plate and wherein each of the stripe-shaped holes is separated by a distance equal to about twice the width of the holes.
