Display device keeping a distance between a light emitting layer and a counter substrate uniformly

摘要

A display device includes a first substrate, pixel electrodes located in correspondence with pixels above the first substrate, a first partition covering ends of a group of the pixel electrodes, a second partition covering ends of another group of the pixel electrodes, the second partition being lower than the first partition, a solid filler located above the first partition and the second partition, and a second substrate facing the first substrate, the second substrate being away from the first substrate by a distance kept by the first partition, the second partition and the filler.
