Official abstract text for this publication.
A novel display panel that can be used as a reflective display panel in an environment with strong external light and as a self-luminous display panel in a dim environment, for example and that has low power consumption and is highly convenient or reliable is provided. The display panel includes a pixel and a substrate that supports the pixel. The pixel includes a first display element (e.g., a reflective liquid crystal element) that includes a reflective film having an opening as a first conductive film and a second display element (e.g., an organic EL element) that emits light to the opening.
Opening claim text (preview).
1 . A display panel comprising: a pixel comprising: a first display element comprising a reflective film; and a second display element; and a substrate configured to support the pixel, wherein the first display element and the second display element overlap each other, wherein the first display element is configured to control transmission of external light, and the reflective film is configured to reflect the external light, wherein the reflective film has an opening, and wherein the second display element is configured to emit light to the opening. 2 . A method of manufacturing a display device comprising: preparing an EL panel supported by a process substrate, the EL panel comprising a light emitting element and a first transistor electrically connected to the light emitting element; separating the process substrate from the EL panel to expose an insulating film which covers the light emitting element; and attaching the EL panel to a liquid crystal panel with a bonding layer therebetween, the liquid crystal panel comprising a liquid crystal element and a second transistor electrically connected to the liquid crystal element, wherein the EL panel is attached to the liquid crystal panel so that the light emitting element and the liquid crystal element overlap with each other. 3 . The method according to claim 2 , wherein the first transistor comprises a channel region which comprises an oxide semiconductor. 4 . A display device comprising a pixel, the pixel comprising: a first transistor formed on a first insulating film; a first display element comprising a reflective conductive film and a liquid crystal material adjacent to the reflective conductive film, wherein the reflective conductive film includes an opening and is electrically connected to the first transistor; a second transistor over a second insulating film; a second display element electrically connected to the second transistor, the second display element comprising a light emitting layer; a third insulating film covering the second display element, wherein the first display element and the second display element are bonded to each other through a bonding layer comprising a resin, wherein the bonding layer is located between the first transistor and the second transistor and is in contact with the third insulating film, and wherein the pixel is configured to emit light from the light emitting layer through the opening of the reflective conductive film. 5 . The display device according to claim 4 , wherein each of the first transistor and the second transistor has a channel region comprising an oxide semiconductor material.
