Display panel and display device
View Patent ↗A display panel includes: a substrate on which a plurality of feed terminals corresponding to a plurality of pixels are provided; a plurality of pixel electrodes corresponding to the respective pixels; a common electrode common to the pixels; and a plurality of light-emitting layers corresponding to the respective pixels and provided between the pixel electrodes and the common electrode. In plan view, within each of the pixels, the light-emitting layer and the feed terminal do not overlap, feed terminals of each column of pixels are provided in a column, and the common electrode is electrically connected to conductive layers, the conductive layers each having a shape of a line that overlaps a corresponding one of the columns of feed terminals. Accordingly, the display panel achieves a high aperture ratio even with the conductive layers formed therein.
1. A display panel having a plurality of pixels arranged in rows and columns, the display panel comprising:
a substrate on which a plurality of feed terminals corresponding to the respective pixels are provided;
an insulation layer provided on the substrate such that at least the feed terminals are free of the insulation layer;

a common electrode common to the pixels and provided continuously above the pixel electrodes; and
a plurality of light-emitting layers corresponding to the respective pixels and provided between the pixel electrodes and the common electrode, wherein
in plan view,
within each of the pixels, the light-emitting layer and the feed terminal do not overlap,
feed ten finals of each column of pixels are provided in a column, and
the common electrode is electrically connected to conductive layers, the conductive layers each having a shape of a line that overlaps a corresponding one of the columns of feed terminals.
2. The display panel of claim 1 , wherein
the insulation layer has a plurality of openings, the openings each having a shape of a line that overlaps a corresponding one of the columns of feed terminals,
the openings allow the feed terminals to be free of the insulation layer, and
at least a bottom portion of each of the conductive layers fits within a corresponding one of the openings.
3. The display panel of claim 1 , wherein
in plan view,
in at least one pair of adjacent columns of pixels from among the columns of pixels, feed terminals of pixels that are adjacent to each other row-wise face each other.
4. The display panel of claim 1 , wherein
the conductive layers are formed over the common electrode.
5. The display panel of claim 1 , wherein
a value obtained by dividing a volume resistivity of a conductive material of the conductive layers by a thickness of each of the conductive layers is smaller than a value obtained by dividing a volume resistivity of a conductive material of the common electrode by a thickness of the common electrode.
6. The display panel of claim 1 , wherein
the conductive layers are layers formed by an application method.
7. The display panel of claim 1 , wherein
each of the conductive layers is continuous and completely overlaps the feed terminals belonging to the corresponding column.
