    • An active matrix display device has an optical layer (7,9,11) comprising a mixture of an electro-optical material and a polymer precursor. An upper surface of the active plate comprises an array of wells (70) such that the upper surface has higher (72) and lower regions, and the optical layer mixture is provided over the active plate. The optical layer is exposed to a stimulus for polymerizing the polymer precursor into a polymer layer constituted by a top surface (9) and by side walls (11), thereby enclosing the electro-optical material between the polymerized material and the active plate to define display pixels. Enclosed bodies of electro-optical material defining display pixels are thus provided over the lower regions. This method uses the processing of the active plate to define wells (70) which provide a height difference which can be used to provide alignment of enclosed display pixels cells. This avoids the need for an alignment mask during the deposition and exposure of the optical layer. In an embodiment of the invention,a layer (74) having affinity to the polymer precursor is provided on the higher regions in a stamping step before exposing the otical layer to the stilus.
    • 有源矩阵显示装置具有包含电光材料和聚合物前体的混合物的光学层(7,9,11)。 活性板的上表面包括孔阵列(70),使得上表面具有较高(72)和较低的区域,并且光学层混合物设置在活性板上。 将光学层暴露于用于将聚合物前体聚合成由顶表面(9)和侧壁(11)构成的聚合物层的刺激,从而将聚合材料和活性板之间的电光材料包围以限定 显示像素。 因此,限定显示像素的电光材料的封闭体被提供在下部区域上。 该方法使用活性板的处理来定义提供高度差的孔(70),其可用于提供封闭的显示像素单元的对准。 这避免了在光学层的沉积和曝光期间对对准掩模的需要。 在本发明的一个实施方案中,在将所述纤维层暴露于st状物之前,在冲压步骤中的较高区域上提供对聚合物前体具有亲和力的层(74)。
