Abstract

A display device includes a color filter substrate, an array substrate, a liquid crystal layer, a protection layer, and a plurality of main spacers. The color filter substrate includes a display region, a hole frame region, and a hole region. Further, in a thickness direction of the hole region of the color filter, an organic flattening film is present on a surface of the array substrate on the color filter substrate side at parts corresponding to positions of the main spacers.

Claims (15)

1. A display device comprising:

a color filter substrate including a display region, a hole frame region, and a hole region and including a plurality of color filters;

an array substrate facing the color filter substrate and including an organic flattening film formed on a surface on a side close to the color filter substrate;

a liquid crystal layer sandwiched between the color filter substrate and the array substrate;

a protection layer configured to protect the plurality of color filters, the protection layer being arranged between the color filter substrate and the liquid crystal layer; and

a plurality of spacers arranged between the protection layer and the array substrate,

wherein the organic flattening film is present at parts corresponding to the positions of the plurality of spacers in a thickness direction of the hole region of the color filter substrate.

2. The display device according to claim 1 ,

wherein the protection layer is present at the parts corresponding to the positions of the plurality of spacers in the thickness direction of the hole region of the color filter substrate.

3. The display device according to claim 2 ,

wherein the plurality of color filters are present at the parts corresponding to the positions of the plurality of spacers in the thickness direction of the hole region of the color filter substrate.

4. The display device according to claim 3 ,

wherein one of the plurality of color filters that transmits white light is provided in the hole region of the color filter substrate.

5. The display device according to claim 1 ,

wherein, in the hole region of the color filter substrate, the plurality of spacers are arranged at a density substantially the same a density in the display region and the hole frame region.
