Abstract

A liquid crystal display device includes a counter substrate having a glass substrate, a color layer on the glass substrate, an overcoating layer on the color layer, and a counter protrusion and a counter wall protrusion on the overcoating layer. The counter protrusion is located in an image display region. The counter wall protrusion is located in a peripheral region enclosing the image display region. The counter protrusion and the counter wall protrusion are of substantially a same height. A first protrusion distance from the glass substrate to a top of the counter protrusion is shorter than a second protrusion distance from the glass substrate to a top of the counter wall protrusion. According to the liquid crystal display device configured as above, an outer periphery of a display panel does not bend.

Claims8

Dependent claims

A display device, comprising:

a counter substrate including a first insulation substrate, a color filter layer on the first insulation substrate, an overcoating layer on the color filter layer, and a first protrusion and a second protrusion on the overcoating layer, wherein
the first protrusion is located in an image display region,
the second protrusion is located in a peripheral region enclosing the image display region,
the first protrusion and the second protrusion are of substantially a same height,
a first protrusion distance from the first insulation substrate to a top of the first protrusion is shorter than a second protrusion distance from the first insulation substrate to a top of the second protrusion,
a first layer of the color filter layer in the second protrusion has multiple slits each extending along an outer periphery of the counter substrate,
a second layer of the color filter layer in the second protrusion is laminated to fully cover the first layer of the color filter layer to get into the slits of the first layer, and
the slits of the first layer overlap the second protrusion.
