Abstract

An electronic device display may have a color filter layer and a thin film transistor layer. A layer of liquid crystal material may be interposed between the color filter layer and the thin film transistor layer. A layer of polarizer may be laminated onto the surface of the color filter layer. Laser trimming may ensure that the edges of the polarizer are even with the edges of the color filter layer. The thin film transistor layer may have an array of thin film transistors that control pixels of the liquid crystal material in the display. Driver circuitry may be used to control the array. The driver circuitry may be encapsulated in a planarized encapsulant on the thin film transistor layer or may be mounted to the underside of the color filter layer. Conductive structures may connect driver circuitry on the color filter layer to the thin film transistor layer.
