Abstract:
A display device includes a first substrate having a plurality of TFTs, a passivation film, and a plurality of pixel electrodes, and a second substrate arranged with a gap with the first substrate. The passivation film has a plurality of contact holes, and the plurality of pixel electrodes are connected to the plurality of TFTs via the plurality of contact holes. The second substrate has a plurality of columnar spacers for ensuring the gap with the first substrate, and a plurality of columnar projections for misalignment prevention formed at positions corresponding to the contact holes. The number of the plurality of columnar projections is less than the number of the plurality of columnar spacers.
