Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device on which a color filter with columnar spacers is mounted, which has satisfactory load resistant properties and in which display defects due to low temperature bubbling are hardly created. SOLUTION: The load resistant properties are enhanced by using a plurality of columnar spacers 43 and 44 corresponding to one pixel of R, G or B and having heights different from each other, providing the plurality of columnar spacers on every other pixel and previously setting up the heights of respective spacers so that a spacer 4 having a smaller height also receives external load together with a spacer 3 having a larger height within the range of elastic deformation of the spacer 3 having a larger height when the spacer 3 is contracted by the external load. Since contraction of a cell gap is absorbed by only the spacer having a larger height at low temperatures, the cell gap is contracted corresponding to the temperature and the display defect due to low temperature bubbling can be reduced.

Abstract translation: 要解决的问题：提供一种液晶显示装置，其上安装有柱状间隔件的滤色器，其具有令人满意的耐负荷性能，并且几乎不产生由于低温起泡引起的显示缺陷。 解决方案：通过使用对应于R，G或B的一个像素并且具有彼此不同的高度的多个柱状隔离物43和44来​​增强耐负荷性质，在每隔一个像素上提供多个柱状间隔物并预先设置 各间隔件的高度使得当间隔件3被外部的收缩时，具有较小高度的间隔件4也与具有较大高度的间隔件3的弹性变形范围内具有较大高度的间隔件3一起接受外部载荷 加载。 由于单元间隙的收缩仅在低温下仅具有较高高度的间隔物而被吸收，所以单元间隙对应于温度而收缩，并且可以降低由于低温起泡引起的显示缺陷。

Then, a passivation insulation film 7, covering the semiconductor layers 4a and 4b, is formed. After the formation of the channel part and before the formation of the passivation insulation film 7, a first plasma treatment 16 is executed by using a first gas (gaseous oxygen, for instance) and a second plasma treatment 17 is executed further by using a second gas (gaseous hydrogen, for instance).

Abstract: A liquid crystal display panel of the type having reflection electrodes tends to have an image-forming plane undesirably yellowed due to the wavelength dependency of transparency observed in an orientation layer on the reflection electrodes; aluminum-neodymium alloy, which has neodymium content between 5 weight % to 10 weight %, is deposited on an inter-layered insulating layer at the substrate temperature equal to or less than 170 degrees in centigrade for the reflection electrodes so that the surface morphology is represented by average pitches equal to or less than 1 micron; even though the orientation layer has the wavelength dependency of transparency, the reflection electrodes make the optical path in the orientation layer equalized so that the image-forming plane is not yellowed.
