Abstract

Reflection layers are arranged for respective pixels with predetermined intervals in a row direction (X direction) and a column direction (Y direction) in a display region, and, subsequently to the display region, are arranged in the same manner with the predetermined intervals in the row direction (X direction) and the column direction (Y direction) also in a peripheral region around the display region. First electrodes, first light path adjusting layers, and second light path adjusting layers are arranged for the respective pixels in the display region, and are arranged so as to correspond to the respective reflection layers also in the peripheral region. The respective reflection layers are partially connected to each other in the peripheral region and are electrically connected to a second electrode at a cathode potential.

Claims (26)

1. An electro-optical device comprising:

a first conductive layer that is provided in a display region;

a second conductive layer that is provided in the same layer as the first conductive layer and in a peripheral region as a region around the display region;

a third conductive layer that is provided in the display region so as to overlap with the first conductive layer;

a fourth conductive layer that is provided in the same layer as the third conductive layer and in the peripheral region so as to overlap with the second conductive layer;

a fifth conductive layer that is provided in the display region so as to overlap with the third conductive layers;

a sixth conductive layer that is provided in the same layer as the fifth conductive layer and in the peripheral region so as to overlap with the fourth conductive layers;

a first insulating layer that is arranged between the first conductive layer and the third conductive layer;

a second conductive layer that is arranged between the second conductive layer and the fourth conductive layer; and

a light-emitting functional layer that is arranged between the third conductive layer and the fifth conductive layer,

wherein the first conductive layer and the second conductive layer are formed with a light-reflective conductive material and are electrically connected with each other.

2. The electro-optical device according to claim 1 , wherein

the second conductive layer is supplied a cathode potential or a ground potential.
