A process for producing a display device includes (a) a providing an area having affinity for a partition wall precursor higher than a surrounding area at an outermost surface of a first substrate, (b) providing an area having affinity for a partition wall precursor corresponding to the area of the first substrate at an outermost surface of a second substrate, (c) disposing the first substrate and the second substrate opposite to each other with a spacing and filling the spacing with a liquid containing the partition wall precursor, (d) collecting the partition wall precursor in a spacing between the areas of the first and second substrates, and (e) fixing the collected partition wall precursor. Such a partition wall has a high adhesiveness and prevents charged particles from entering an adjacent pixel even if contained in a liquid.
