A method of producing plural pixellated display devices, each having a first component comprising an array of independently controllable pixel electrodes; and a second component comprising an array of pixel filters comprising different types of pixel filters of differing optical transmission characteristics, each pixel filter being associated with a respective one of said pixel electrodes. The first component has some distortion within the array of pixel electrodes causing a variation in pixel electrode pitch between different regions of the array. The second component is applied to the first component to provide misalignment between an alignment reference position on the first component and an alignment reference position on the second component. An array of pixel filters is formed in a neutral framework having a separation distance between each pixel filter that prevents any pixel filter of the array of pixel filters overlapping with more than one of said pixel electrodes.
