18 Claims

1. A display device comprising a panel, the panel comprising:

a pixel, the pixel comprising:

a light-emitting element;

a microlens; and

a color conversion layer,

wherein the light-emitting element comprises:

a first electrode;

a layer containing a light-emitting material over the first electrode; and

a second electrode over the layer containing a light-emitting material,

wherein the microlens is interposed between the light-emitting element and the color conversion layer,

wherein the microlens has a convex portion,

wherein the light-emitting element is configured to emit a first light,

wherein the color conversion layer is configured to convert the first light into a second light,

wherein an insulating film is provided over the first electrode,

wherein the insulating film comprises an opening portion overlapping with the light-emitting element,

wherein the opening portion has an inclined surface on a first side wall,

wherein the inclined surface is configured to reflect the first light toward the microlens,

wherein the convex portion of the microlens is covered by a sealant, and

wherein the microlens has an inclined side surface which is not covered by the sealant.
