Border Masking Structures for Liquid Crystal Display

A display, comprising:

• a thin-film transistor layer;
• a color filter layer;
• a liquid crystal layer between the thin-film transistor layer and the color filter layer;
• and
• a backlight light guide plate that provides backlight for the display, wherein the color filter layer is interposed between the liquid crystal layer and the backlight light guide plate, wherein the thin-film transistor layer has a transparent substrate layer, wherein the thin-film transistor layer has a patterned black masking layer on the transparent substrate layer, wherein the thin-film transistor layer has a spin-on glass planarization layer that covers the patterned black masking layer, and wherein the thin-film transistor layer has a thin-film transistor circuitry layer on the spin-on glass planarization layer.

An electronic device, comprising:

• a housing;
• and
• a display in the housing, wherein the display has a rectangular active area and has an inactive border area that runs along a peripheral edge of the rectangular active area, wherein the housing is configured so that the inactive border area is not overlapped by portions of the housing, wherein the display comprises:
• a backlight structure that provides backlight for the display;
• a thin-film transistor layer having a patterned black masking layer, a clear planarization layer covering the black masking layer, and a layer of thin-film transistor circuitry on the planarization layer;
• a color filter layer having a clear color filter layer substrate, wherein the color filter layer substrate is between the backlight structure and the thin-film transistor layer;
• a light blocking structure on a lower surface of the clear color filter layer substrate in the inactive border area;
• and
• a liquid crystal layer between the color filter layer and the thin-film transistor layer.
