摘要:
The invention provides a color filter which includes a light shielding region having sufficient light shielding performance, and a transmitting region having no color mixing, and which has high contrast without pixel defect and irregularity in color tone. A color filter of the present invention can include a pixel region and a spotting precision test region. The pixel region includes a light shielding region and a transmitting region partitioned by the light shielding region. The light shielding region includes a first light shielding layer. The transmitting region includes a color element. The spotting precision test region is positioned apart from the pixel region and includes a second light shielding layer and a spotting precision test layer provided to cover at least the second light shielding layer. The spotting precision test layer region includes an evaluation region partitioned by the second light shielding layer.
