Abstract

A display panel includes a plurality of pixels and a plurality of power lines. The plurality of pixels are disposed in a matrix and include respective light-emitting devices and respective pixel circuits. The pixel circuits are disposed at unequal intervals in a column direction. The light-emitting devices are provided to allow light-emitting regions of the respective light-emitting devices to have an equal interval in the column direction. The plurality of power lines are extended in a row direction and each supply a current flowing into the light-emitting device. Each one of the plurality of power lines is disposed for a plurality of pixel rows. A spacing between the pixel circuits in the column direction is relatively large at a portion facing one of the power lines. A spacing between the pixel circuits in the column direction is relatively small at a portion facing wiring other than the power lines.

Claims (21)

1. A display panel comprising:

a plurality of pixels that are disposed in a matrix and include respective light-emitting devices and respective pixel circuits, the pixel circuits being disposed at unequal intervals in a column direction, the light-emitting devices being provided to allow light-emitting regions of the respective light-emitting devices to have an equal interval in the column direction; and

a plurality of power lines that are extended in a row direction and each supply a current that flows into the light-emitting device, and each one of the plurality of power lines being disposed for a plurality of pixel rows, wherein

a spacing between the pixel circuits in the column direction is relatively large at a portion facing one of the power lines, and a spacing between the pixel circuits in the column direction is relatively small at a portion facing wiring other than the power lines.

2. The display panel according to claim 1 , wherein

each of the pixels is one of a plurality of subpixels disposed side by side in the row direction, the subpixels being included in a display pixel, and

each one of the plurality of power lines is disposed for a plurality of subpixel rows.

3. The display panel according to claim 1 , wherein

each of the pixels is one of a plurality of subpixels disposed in a matrix of two by two or more, the subpixels being included in a display pixel, and

each one of the plurality of power lines is disposed for a plurality of subpixel rows included in a display pixel row.

4. The display panel according to claim 1 , wherein the plurality of light-emitting devices are disposed at an equal interval in the column direction.

5. The display panel according to claim 1 , wherein the plurality of light-emitting devices are disposed at unequal intervals in the column direction.

6. The display panel according to claim 1 , further comprising a shielding layer between the light-emitting device and the pixel circuit, the shielding layer preventing the light-emitting device and the pixel circuit from being coupled with each other.

7. A display unit provided with a display panel and a drive circuit that drives the display panel, the display panel comprising:

a plurality of pixels that are disposed in a matrix and include respective light-emitting devices and respective pixel circuits, the pixel circuits being disposed at unequal intervals in a column direction, the light-emitting devices being provided to allow light-emitting regions of the respective light-emitting devices to have an equal interval in the column direction; and

a plurality of power lines that are extended in a row direction and each supply a current that flows into the light-emitting device, and each one of the plurality of power lines being disposed for a plurality of pixel rows, wherein

a spacing between the pixel circuits in the column direction is relatively large at a portion facing one of the power lines, and a spacing between the pixel circuits in the column direction is relatively small at a portion facing wiring other than the power lines.

8. An electronic apparatus provided with a display unit, the display unit including a display panel and a drive circuit that drives the display panel, the display panel comprising:

a plurality of pixels that are disposed in a matrix and include respective light-emitting devices and respective pixel circuits, the pixel circuits being disposed at unequal intervals in a column direction, the light-emitting devices being provided to allow light-emitting regions of the respective light-emitting devices to have an equal interval in the column direction; and

a plurality of power lines that are extended in a row direction and each supply a current that flows into the light-emitting device, and each one of the plurality of power lines being disposed for a plurality of pixel rows, wherein

a spacing between the pixel circuits in the column direction is relatively large at a portion facing one of the power lines, and a spacing between the pixel circuits in the column direction is relatively small at a portion facing wiring other than the power lines.
