Column substrate can be the array substrate of Organic Light Emitting Diode, or the array substrate of liquid crystal display panel.
For example, as shown in Figure 1B, display base plate 100 further includes pixel unit 130, it is arranged on underlay substrate 110, and position
In pixel display area 102.Figure 1B show schematically pixel unit 130 positioned at the first optical layer 120 and underlay substrate 110 it

Change original optical path after layer, and this part is changed at least partly emitting from clear area in the image light of optical path, leads to
It crosses the position in original vision stain and is shown display integrality to realize entire display base plate.
For example, if the image light with the hithermost pixel unit in clear area does not pass through the first light deflection portion and second
Optical layer, then it can be shown in pixel display area close to the edge of clear area, and in the image light of the pixel unit by
After one light deflection portion and the second optical layer deflect to clear area, which is then shown in clear area, that is, first
Light deflection portion and the second optical layer will deflect to clear area close to the image light that the edge of clear area is shown in pixel display area
It is interior.The present embodiment to the quantity of the pixel unit shown in clear area with no restrictions, as long as being able to achieve entire display base plate
