Abstract
The present invention aims at the suppression of chromaticity irregularities and brightness irregularities by reflecting a result of an analysis of film forming misalignment of an organic EL layer. For this end, a drive circuit chip 6 is mounted on a lower side of a display panel 4, and a terminal portion 7 for connection with an external device (a host device) is mounted on an end edge of the lower side of a display panel 4. Film forming misalignment vectors (indicated by arrows) of sub pixels at an arbitrary point in a display region 5 fall within a first quadrant and an angle made between the vectors falls within 90°.
Claims5
An organic EL display device including a display panel which is formed by arranging pixels constituted of a plurality of organic EL elements on an active substrate in a matrix array, wherein
- the organic EL element is provided to the active substrate for every unit color pixel which is constituted of a plurality of sub pixels, and is constituted of one electrode in which a sub pixel opening is formed, an organic EL layer which is formed on one electrode, and another electrode which is formed on the organic EL layer while covering the organic EL layer, and
- angles made between vectors indicative of misalignments of the film forming centers of respective organic EL layers relative to the centers of the sub pixel openings at an arbitrary position on the display panel fall within 90°.
