Abstract

An active matrix liquid crystal display device of the invention includes a liquid crystal display panel operating in a normally black mode having a first substrate provided with a color filter and a second substrate provided with an active matrix array, wherein the first substrate is provided with a laminated colored layer with three colors, a laminated colored layer with two colors and a colored layer with one color in a frame part surrounding a display area without being provided with a black matrix, and the second substrate is provided with a conductive film formed in a region which is opposed to the laminated colored layer with two colors and the colored layer with one color, between the display area and the laminated colored layer with three colors.

Claims (6)

1. An active matrix liquid crystal display device comprising:

a liquid crystal display panel operating in a normally black mode including a first substrate provided with a color filter and a second substrate provided with an active matrix array,

wherein said first substrate is provided with a laminated colored layer with three colors, a laminated colored layer with two colors in a frame part surrounding a display area without being provided with a black matrix, and said second substrate is provided with a conductive film formed in a region which is opposed to said laminated colored layer with two colors, between said display area and said laminated colored layer with three colors.

2. An active matrix liquid crystal display device comprising:

a liquid crystal display panel operating in a normally black mode including a first substrate provided with a color filter and a second substrate provided with an active matrix array,

wherein said first substrate is provided with a laminated colored layer with three colors and a laminated colored layer with two colors in a frame part surrounding a display area without being provided with a black matrix, and said second substrate is provided with a conducting film formed in a region which is opposed to a boundary part between said display area and said laminated colored layer with two colors, and a boundary part between said laminated colored layer with three colors and said laminated colored layer with two colors.
