The display panel includes a light emitting layer configured to output images, and a protective layer configured to protect the display panel. The light emitting layer includes a display region having a first pixel density, a first transmissive region having a second pixel density that is less than the first pixel density, and a second transmissive region having a third pixel density that is less than the second pixel density. The first transmissive region is configured to interface with a first sensor and the second transmissive region is configured to interface with a second sensor, wherein a function of the first sensor requires less light than a function of the second sensor. ## Claims ### Claim 1 A display panel, comprising: a display region having a first pixel density; a first transmissive region having a second pixel density that is less than the first pixel density; and a second transmissive region having a third pixel density that is less than the second pixel density, wherein the first transmissive region overlaps a first sensor, and the second transmissive region overlaps a second sensor, wherein the first sensor senses infrared light, and the second sensor senses visible light. ### Claim 2 (depends on 1) The display panel of claim 1, wherein the first transmissive region and the second transmissive region differ in shape or size. ### Claim 3 (depends on 1) The display panel of claim 1, wherein the first transmissive region and the second transmissive region have different pixel arrangements. ### Claim 4 (depends on 1) The display panel of claim 1, wherein the first transmissive region does not include a light transmission part and the second transmissive region includes the light transmission part. ### Claim 5 (depends on 1) The display panel of claim 1, wherein a transmittance of the second transmissive region is higher than the transmittance of the first transmissive region and the transmittance of the first transmissive region is higher than the transmittance of the display region. ### Claim 6 (depends on 1) The display panel of claim 1, wherein an imaginary straight line on a plane passes through the display region, the first transmissive region, and the second transmissive region. ### Claim 7 (depends on 1) The display panel of claim 1, wherein the first sensor includes a light emitting unit and a light reception unit. ### Claim 8 (depends on 1) The display panel of claim 1, further comprising: A protective layer configured to protect the display panel; and A touch layer configured to detect touch input on the protective layer. ### Claim 9 (depends on 8) The display panel of claim 8, further comprising: A color filter layer configured to absorb a portion of a wavelength of a reflected light on the touch layer. ### Claim 10 (depends on 1) The display panel of claim 1, wherein the first sensor and the second sensor are formed as one integrated module. ### Claim 11 A display panel, comprising: a light emitting layer configured to output images; and a touch layer configured to detect touch input on the light emitting layer; wherein the touch layer includes a first region having a first touch sensor electrode density, and a second region having a second touch sensor electrode density that is less than the first touch sensor electrode density, wherein at least one light sensor overlaps the second region. ### Claim 12 (depends on 11) The display panel of claim 11, wherein the second region includes a second-1 region having a second-1 touch sensor electrode density and a second-2 region having a first-2 touch sensor electrode density that is less than the first-1 touch sensor electrode density. ### Claim 13 (depends on 12) The display panel of claim 12, wherein the first region corresponds to a first pixel area having a first pixel density, the second-1 region corresponds to a second pixel area having a second pixel density that is less than the first pixel density, and the second-2 region corresponds to a third pixel area having a third pixel density that is less than the second pixel density. ### Claim 14 (depends on 11) The display panel of claim 11, wherein the light sensor includes a first light sensor which requires a first transmittance and a second light sensor which requires a second transmittance lower than the first transmittance are disposed under the display panel, the first light sensor is disposed in the third pixel region, and the second light sensor is disposed in the second pixel region. ### Claim 15 (depends on 11) The display panel of claim 11, wherein an electrode of a touch sensor disposed at the second touch sensor electrode density has a smaller size than an electrode of a touch sensor disposed at the first touch sensor electrode density. ### Claim 16 (depends on 11) The display panel of claim 11, further comprising: A color filter layer configured to absorb a portion of a wavelength of a reflected light on the touch layer.
