Title:
液晶表示装置
Document Type and Number:
Japanese Patent JP6845369
Kind Code:
B2
Abstract:
When a columnar spacer is provided in a region overlapping with a TFT, there is a concern that pressure will be applied when attaching a pair of substrates to each other, which may result in the TFT being adversely affected and a crack forming. A dummy layer is formed of an inorganic material below a columnar spacer which is formed in a position overlapping with the TFT. The dummy layer is located in the position overlapping with the TFT, so that pressure applied to the TFT in a step of attaching the pair of substrates is distributed and relieved. The dummy layer is preferably formed of the same material as a pixel electrode so that it is formed without an increase in the number of processing steps.
