Display device

摘要

Minimum distances between features in high resolution liquid crystal displays are described. Specifically, minimum distances between a column spacer and contact holes in adjacent pixels are described. Maintaining a minimum distance between a column spacer and a contact hole prevents the column spacer from being unintentionally placed in a nearby contact hole. This unintentional placement can be more likely in high resolution displays due to reduced pixel size.

主权项

1. A liquid crystal display device pixel comprising:
a first alignment layer disposed over a first substrate; a second alignment layer disposed below a second substrate; a passivation layer disposed below the first alignment layer over the first substrate, the passivation layer defining a contact hole, the contact hole exposing a portion of a drain electrode of a thin film transistor; a first column spacer disposed between the first alignment layer and the second alignment layer, the first column spacer having a first end proximate the first alignment layer and a second end proximate the second alignment layer, wherein a minimum lateral distance between the first end of the first column spacer and the contact hole is a sum of a predetermined design value plus an alignment margin.
