Method of manufacturing organic EL device, organic EL device, and electronic apparatus
A method of manufacturing an organic EL device that is capable of reducing the manufacturing cost by effectively using the material is provided. In the method of manufacturing the organic EL device including a white-light-emitting layer and a color filter, the white-light-emitting layer is formed by using a liquid droplet ejection method. Further, the color filters are also formed by using the liquid droplet ejection method. As a result, it is possible to reduce waste of the material and the manufacturing time.
1. A method of manufacturing an organic EL device comprising a plurality of first pixel electrodes, a plurality of second pixel electrodes, a counter electrode, a white-light-emitting layer for emitting white light components, a color light-emitting layer for emitting color light components, and color filters, comprising:
forming a first bank layer, the first bank layer having first openings that are formed at positions at which the white-light-emitting layer is arranged;
forming the color filters by ejecting a first liquid material containing a material for forming the color-light-emitting layer in the first openings by using a liquid droplet ejection method;
forming the plurality of first pixel electrodes and the plurality of second pixel electrodes, the plurality of first pixel electrodes on the color filters and the plurality of second pixel electrodes on the first bank at which the color-light-emitting layer is arranged;
forming a second bank layer, the second bank layer having second openings and third openings, the second openings are formed at positions at which the plurality of first pixel electrodes are arranged and the third openings are formed at positions at which the plurality of second pixel electrodes are arranged;
forming the white-light-emitting layer on the plurality of first pixel electrodes by ejecting a liquid material containing a material for forming the white-light-emitting layer in the second openings by using a liquid droplet ejection method;
forming the color-emitting-layer on the plurality of second pixel electrodes by ejecting a liquid material containing a material for forming the color-light-emitting layer in the third openings by using a liquid droplet ejection method; and
