Organic EL display device

Abstract

An organic EL display device includes a first substrate, and a second substrate having one side laminated to one side of the first substrate by a resin seal. The first substrate includes a plurality of pixels, wherein each of the plurality of pixels includes a first electrode surrounded by a bank film made of insulating material, an organic light emitting material formed over the first electrode, a second electrode formed over the organic light emitting material, and a thin film transistor formed under the bank film which electric current flowing between the first and the second electrodes. A material layer which absorbs light having a wavelength of not less than 350 nm and not greater than 410 nm is formed on an other side of the first substrate or the second substrate.

1 . An organic EL display device comprising: 
 a first substrate; and    a second substrate laminated to one side of the first substrate by a resin seal;    wherein the first substrate comprises a plurality of pixels;    wherein each of the plurality of pixels comprises a first electrode surrounded by a bank film made of insulating material, an organic light emitting material formed over the first electrode, a second electrode formed over the organic light emitting material, a thin film transistor formed under the bank film and controlling electric current flowing between the first and the second electrodes;    wherein the first electrode is transparent; and    wherein a material layer which absorbs light having a wavelength of not less than 350 nm and not greater than 410 nm is formed on an other side of the first substrate.    
     
     
         2 . An organic EL display device according to  claim 1 , wherein the bank film overlaps with the material layer.
