Abstract

A display device with improved viewing angle characteristics is provided. A display device with suppressed mixture of colors between adjacent pixels is provided. The display device includes a first coloring layer, a second coloring layer, and a structure body therebetween. The structure body has a portion closer to a display surface side than a bottom surface of the first coloring layer or a bottom surface of the second coloring layer.

Claims (54)

second structure bodies extending along a second direction intersecting with the first direction,

wherein the first pixel and the second pixel each comprises a transistor and a liquid crystal element electrically connected to the transistor,

wherein a first conductive layer serving as a first electrode of the liquid crystal element overlaps with a second conductive layer serving as a second electrode of the liquid crystal element with an insulating layer interposed therebetween,

wherein one of the first structure body overlaps with a third conductive layer serving as a gate of the transistor in a plan view,

wherein the first structure bodies and the second structure bodies are apart from each other with a distance therebetween in the plan view,

wherein the one of the first structure body overlaps with a region between the first coloring layer and the second coloring layer in the plan view,
