Abstract
The present application provides a display panel and a method of fabricating thereof. The display panel includes a light emitting layer and a touch layer. The touch layer includes a touch trace layer and a filter structure, and the touch trace layer includes a plurality of gaps. The touch trace layer includes a first metal layer, a light shielding layer and a second metal layer, and an area of the light shielding layer is greater than an area of the first metal layer. Projections of the plurality of gaps on a light emitting surface of the display panel separates with a projection of the first metal layer and the second metal layer on the light emitting layer.
Claims13
