摘要： Disclosed is an electro-optic element, such as a liquid crystal, which exhibits optically rotatory dispersion and in which a pair of phase difference films (8, 9) having generally orthogonal stretching axes are disposed between a pair of polarizing plates (1, 2). The disposition of stretching axis directions (10, 11), arrangements (6, 7) of a liquid crystal cell (5) and transmission axis directions (3, 4) of the polarizing plates (1, 2) are optimized to achieve an increase in the angle of visibility, an increase in the contrast and improvements in color tones.

摘要： Molecules of the liquid crystal filled in the liquid crystal display panel are orientated along the rubbing directions of the upper and the lower substrates and the orientation thereof tends to be twisted in one direction. The reverse domain that the orientation is twisted in the reverse direction occurs at portions of the liquid crystal. Though the reverse domain may be prevented from occurring by rubbing the substrates stronger, it is impossible to sufficiently rub the surfaces of the respective substrates since the substrates are provided with picture element electrodes thereon so that the surfaces are uneven. The liquid crystal display panel is heated to a transformation point so as to change into an isotropic phase after filling the liquid crystal, then is cooled rapidly, whereby there can be obtained a liquid crystal display panel in which the twisted directions of the orientation of the liquid crystal molecules are uniform.
摘要翻译：填充在液晶显示面板中的液晶的分子沿着上下基板的摩擦方向取向，并且其取向倾向于在一个方向上扭曲。取向在相反方向上扭转的相反区域发生在液晶的部分。虽然可以通过摩擦基板更强地防止反向畴发生，但是由于基板上设有像素电极使得表面不均匀，不可能充分地摩擦各个基板的表面。将液晶显示面板加热到相变点，使其在充满液晶之后变为各向同性相，然后迅速冷却，由此可以获得液晶显示面板，其中，取向的扭转方向液晶分子是均匀的。

摘要： A liquid crystal panel used for a flat display can be produced at a high yield while scattering of hue and optical interference are vanished to realize a high quality display.
At each interface between adjacent layers (for example between a top substrate (1) and a color filter (8), or between a color filter (8) and an ITO film (4), or the like) the difference of the index of refraction is set to be 0.2 or less.
To that purpose an intermediate layer (12,13) may be inserted between two adiacent layers where the difference of the index of refraction is larger than 0.2.
Alternatively, if a layer has a difference of index of refraction larger than 0.2 with respect to an adjacent layer at either side thereof then its optical path "nd" is chosen to satisfy the relation

n d = N λ 2

where λ denotes a design wavelength, and N a positive integer.
Preferentially λ = 550 nm (green color wavelength).
Still alternatively, a minute rough surface of 0.01-0.5 µm may be formed at any interface where the difference of the index of refraction is larger than 0.2.
摘要翻译：用于平板显示器的液晶面板可以以高产率制造，而色相和光学干涉的散射消失以实现高质量显示。在相邻层之间的每个界面处（例如在顶部基板（1）和滤色器（8）之间，或在滤色器（8）和ITO膜（4）之间等）之间，折射率设定为0.2或更小。为此目的，中间层（12,13）可以插入在折射率差大于0.2的两个附着层之间。或者，如果一层具有相对于其任一侧的相邻层的大于0.2的折射率差，则选择其光路“nd”以满足关系nd =Nλ2，其中λ表示设计波长，并且 N是正整数。优选λ= 550nm（绿色波长）。或者，可以在折射率差大于0.2的任何界面处形成0.01-0.5μm的微小粗糙表面。

摘要： A projection type liquid crystal display unit has dichroic mirrors (53,54) capable of dividing a light from a light source (51) into R, G and B components which are guided along respective light paths. Each of at least two of these light paths is provided with an optical system which includes a pair of polarizing plates, a twist nematic liquid crystal (58,59,60) and at least one phase plate. The angles of the retardation phase axis of the phase plate and light-interruption axes of the polarizing plates or, alternatively, the retardation of the phase plate is determined so as to improve the light-interruption of the liquid crystal panel in light-interruption mode, thereby enhancing contrast of the display image.
